The Strange Jobs People Once Did That Would Confuse Us Today

Imagine walking into a job interview and discovering that the position requires you to wake up before sunrise, collect human waste, deliver it to a farm, and return home knowing that you have contributed to the local economy.

Or imagine being paid to wake people up by tapping their bedroom windows with a long stick. Not metaphorically. Not as a prank. As an actual occupation.

The modern world has some unusual jobs, but history had an entirely different imagination when it came to employment. Before smartphones, electricity, automated factories, and sophisticated delivery networks, people invented careers around problems that most of us barely think about today.

Someone had to light the streets. Someone had to announce the news. Someone had to maintain the town’s clocks. Someone had to remove waste, preserve food, carry messages, and perform countless other tasks that technology would eventually transform or eliminate.

The fascinating part is that these occupations were not necessarily ridiculous to the people who performed them. Many were essential services, and the people doing them possessed specialized knowledge, practical skills, and an understanding of their communities.

Their jobs only seem strange because the world that created them has changed.

History, in a sense, is a giant museum of human problem-solving. Every strange occupation tells us something about the technology people lacked, the systems they built, and the everyday inconveniences they learned to turn into livelihoods.

Here are some of the most fascinating jobs from the past that would leave a modern job applicant wondering whether they had accidentally walked into a historical comedy.

1. The Human Alarm Clock

Before alarm clocks became common household objects, some people made a living by waking others up.

In Britain and Ireland during the nineteenth and early twentieth centuries, these workers were often called knocker-uppers. Their customers were typically factory workers and other employees who needed to wake up at specific times to avoid losing wages or arriving late.

The job was simple in theory: arrive outside a customer’s home and make enough noise to get them out of bed.

In practice, the methods could be surprisingly inventive. Some knocker-uppers tapped on windows with long poles. Others used pea shooters to fire dried peas at upstairs windows. They might continue until the customer responded or otherwise demonstrated that they were awake.

Think about that for a moment.

Today, we can set five alarms on a phone, ask a smart speaker to wake us up, or use a smartwatch that vibrates against our wrist. In the past, someone might have needed to stand outside our bedroom and physically convince us to begin the day.

The knocker-upper was essentially a human notification system.

There was even an interesting economic relationship behind the occupation. Customers were paying for reliability, not simply noise. An alarm that failed to wake a factory worker could mean lost wages or other consequences.

The job also illustrates a recurring pattern in technological history: whenever a basic human need becomes predictable enough, someone finds a way to provide it as a service.

Today, we outsource reminders to software. Yesterday, we outsourced them to people carrying sticks.

2. The Ice Cutter

Imagine living in a world where keeping your food cold requires someone to travel to a frozen lake with specialized tools.

Before electric refrigerators became widespread, natural ice was an important commercial resource. In colder regions, workers harvested ice from frozen lakes, ponds, and rivers during winter.

These ice cutters marked the frozen surfaces into sections, sawed through the ice, and separated enormous blocks. The blocks were then transported, stored in insulated icehouses, and distributed to homes and businesses.

The work required considerable physical effort, knowledge of local conditions, and careful attention to the thickness and quality of the ice.

The harvested ice could be used to cool food, preserve perishable goods, and supply businesses that depended on refrigeration. With suitable insulation and storage, ice harvested during winter could sometimes remain useful well into warmer months.

This was not simply a matter of cutting frozen water. It was an entire supply chain.

Workers needed to identify suitable ice, organize extraction, move heavy blocks, maintain storage facilities, and deliver the product before too much of it melted.

The strange part is that the fundamental objective has not changed. We still need to keep food fresh. We have simply replaced a seasonal harvesting operation with refrigerators, freezers, electrical systems, and industrial cooling equipment.

A modern supermarket manager who runs out of refrigeration capacity might never consider hiring someone to cut a lake into blocks.

Yet, for generations, the availability of natural ice helped determine how people stored food and conducted business.

The ice cutter reminds us that some of the most ordinary conveniences in modern life were once entire industries.

3. The Professional Human Computer

The word computer originally referred to a person who performed calculations.

Long before electronic computers appeared, governments, observatories, research institutions, and businesses employed people to carry out mathematical work by hand.

These human computers performed calculations for astronomy, navigation, engineering, statistics, and other technical fields. Some worked independently, while others operated in teams where large calculations were divided into smaller tasks.

Imagine a workplace where your primary responsibility is to calculate thousands of numbers accurately, check your colleagues’ work, and repeat the process until the final results are reliable.

There is no spreadsheet. No calculator app. No programming language. Just mathematical methods, tables, paper, and considerable concentration.

The occupation required more than basic arithmetic. Depending on the task, workers needed advanced mathematical knowledge, familiarity with calculation methods, and the ability to detect errors.

A single incorrect value could affect a much larger calculation, making verification essential.

The job becomes even more interesting when we consider the transition to electronic computing. The word did not suddenly acquire a completely unrelated meaning. Instead, machines gradually took over tasks that people had previously performed.

Today, when someone says they work in computing, we usually imagine programming, managing databases, designing software, or operating digital systems.

A person who describes themselves as a computer from several centuries ago would have meant something very different.

The historical human computer is a reminder that technological progress often begins by automating a task that somebody has already learned to perform manually.

First, humans develop a method. Then they organize the work. Eventually, they build machines that can execute the method faster.

The machine does not make the original occupation meaningless. It reveals just how much knowledge was hidden inside it.

4. The Night Soil Collector

Modern sanitation systems make it possible to remove household waste through underground pipes, treatment plants, and organized collection services.

For much of history, however, many communities had no equivalent infrastructure.

In places where households relied on privies, cesspits, or other facilities without modern sewer connections, someone had to remove accumulated human waste.

In parts of Britain and elsewhere, workers known as night soil collectors performed this unpleasant but necessary task. The term was particularly associated with the collection of waste from privies and similar facilities, often during nighttime hours.

Why at night?

In some communities, working after dark helped reduce disruption, unpleasant encounters, and the inconvenience associated with transporting waste through populated streets.

The collected material could sometimes be used as agricultural fertilizer, depending on local practices and conditions. This created a connection between urban sanitation and farming that is easy to overlook today.

Of course, the work involved significant health risks, difficult conditions, and considerable physical labor.

It also addressed a problem that no society can simply ignore: waste must go somewhere.

Modern sewage treatment, plumbing, and sanitation services have transformed how this problem is managed. The essential task remains, but the systems surrounding it have become far more sophisticated.

The historical night soil collector would probably be surprised by today’s wastewater treatment plants, just as a modern sanitation engineer might struggle to imagine an entire neighborhood depending on manual waste removal.

And that is the point. Some jobs disappear because the problem disappears. Others disappear because society develops a better way to solve the same problem.

5. The Official Town Crier

Before radio, television, newspapers became widely accessible, and instant digital communication, communities needed ways to distribute public information.

One solution was the town crier.

Town criers announced news, public notices, proclamations, and other information in streets and public gathering places. They often used a bell to attract attention before delivering their announcements.

In some places, criers worked under official authority and communicated information that local governments wanted residents to hear.

The occupation demanded a strong voice, confidence in public settings, and the ability to deliver information clearly enough for people nearby to understand.

Imagine receiving an important announcement today through someone walking down your street, ringing a bell, and shouting the details.

There would be no notification history, no replay button, and no convenient link to the full announcement. If you missed the message, you might need to ask a neighbor what had happened.

The town crier was effectively a human broadcast network.

The role was not entirely about entertainment or spectacle. In communities with limited access to written information, spoken announcements could provide an important public service.

Modern communication systems have dramatically expanded the speed and reach of announcements. A government notice can now be published online, distributed through messaging services, and accessed by people who are nowhere near the place where the news originated.

But the underlying need is familiar: people must receive information they can understand and act upon.

The town crier’s tools were simple. The communication problem was not.

6. The Lamplighter

Picture a city after sunset.

There are no electric streetlights. The roads are becoming dark, shops are closing, and people are preparing to return home.

Then someone walks along the streets carrying a ladder, a lighting tool, and the equipment needed to maintain the lamps.

This was the lamplighter.

In cities that used gas lighting, lamplighters were responsible for lighting street lamps, extinguishing them when required, and sometimes performing routine maintenance.

Their work followed the rhythms of the day. As evening approached, they helped bring light to streets and public spaces. Depending on the lighting system and local arrangements, they returned at other times to maintain or extinguish the lamps.

The job required familiarity with the streets, practical knowledge of the lighting equipment, and attention to routine.

The occupation becomes especially interesting when we compare it with modern infrastructure.

Today, many streetlights operate automatically. Sensors, timers, remote monitoring systems, and centralized controls can reduce the need for individual workers to visit every lamp just to turn it on.

However, modern lighting still requires maintenance. Damaged equipment, electrical faults, and failed components do not repair themselves.

The occupation changed because the technology changed.

The lamplighter’s work was partly a manual control system for a city’s nighttime environment. Modern electrical infrastructure performs much of that control automatically.

There is something poetic about the transition. A worker once had to travel from lamp to lamp to make a city visible after dark. Now, a network of electrical systems can illuminate entire roads at the press of a switch—or according to a schedule that nobody needs to think about.

7. The Phonograph Recordist Who Captured Everyday Sounds

Before modern recording equipment became widely available, capturing and preserving sound was a specialized technical activity.

Early sound-recording professionals worked with technologies that were far less convenient than today’s digital recorders. Depending on the period and equipment, recording could involve wax cylinders, mechanical recording systems, or other physical media.

People recorded music, spoken performances, oral histories, and environmental sounds for entertainment, research, education, and preservation.

Some sound-recording work involved traveling to places where particular voices, musical traditions, languages, or acoustic environments could be documented.

The occupation was especially demanding because recording technology had limitations. Equipment could be bulky, recording time was restricted, and the quality of the result depended on the recording method and surrounding conditions.

Imagine wanting to record a conversation today and discovering that you must prepare a specialized physical medium, carefully position the equipment, and make the most of a short recording opportunity.

There is no unlimited cloud storage. There is no effortless editing timeline. There may not even be a convenient way to make another copy.

The strange thing is that this work helped create the foundation for something we now take for granted: the ability to preserve a moment as sound.

A voice can survive the person who produced it. A musical performance can travel across generations. An announcement can be replayed long after the original event.

Modern audio engineers, sound designers, archivists, and recording artists still perform related work, but digital technology has changed the tools and expanded the possibilities.

The historical recordist reminds us that today’s effortless recording culture rests on generations of experimentation with physical sound.

8. The Human Calculator of the Sea

Before modern navigation systems, sailors relied on a combination of charts, instruments, astronomical observations, and mathematical calculations to determine their positions.

This created demand for people who understood navigation and could perform the calculations required to interpret observations and plan routes.

Navigation specialists and navigators were particularly important on long voyages, where a vessel could spend days or weeks away from recognizable landmarks.

A navigator might use a sextant to measure the angle between a celestial object and the horizon, consult tables, account for time, and calculate an estimated position.

The process was not simply about looking at the stars and guessing.

It depended on mathematical methods, accurate observations, reliable timekeeping, and knowledge of the Earth’s geography.

Errors mattered. A mistake could send a vessel away from its intended route or make it more difficult to identify hazards and landfalls.

Today, satellite-based positioning systems can calculate a vessel’s location with remarkable convenience. Digital charts and electronic navigation equipment also help crews plan and monitor their journeys.

Yet navigation has not become completely effortless. Electronic systems can fail, signals may be unavailable or unreliable, and professional mariners still need to understand routes, instruments, weather, and safety procedures.

The older occupation therefore offers an interesting lesson about automation: replacing a difficult calculation does not eliminate the need to understand the larger system.

A modern sailor may not need to calculate every position by hand, but the ability to recognize when a result is wrong remains valuable.

The historical navigator was not merely a person with a compass. They were a human positioning system, combining observation, mathematics, and experience to solve a problem that still matters today.

9. The Knocker-Up’s More Unexpected Cousin: The Human Telephone Operator

Early telephone systems required people to perform tasks that modern devices handle electronically.

In many telephone exchanges, operators connected callers by manually operating switchboards. A caller would contact the exchange, request a connection, and rely on an operator to connect the appropriate lines.

The operator’s workplace could contain rows of sockets, cords, switches, and indicators. Managing the connections required attention, coordination, and the ability to handle multiple requests.

This was not simply a matter of plugging in wires. Operators needed to understand the exchange’s procedures, respond to callers, and establish the correct connections.

Before automated switching became widespread, human operators were an essential part of telephone infrastructure.

From today’s perspective, the arrangement seems unusual. We tap a name on a screen, and a device establishes a connection across networks that may span continents.

We rarely imagine another person manually connecting our call.

Yet the telephone operator occupied a position between the user and the communication system, much as modern software interfaces stand between people and complex digital infrastructure.

The difference is that many of the operator’s individual actions have been automated.

Interestingly, the occupation also demonstrates that automation often changes the skills a system needs. Telephone operators became less central to routine call connection as switching technology developed, while telecommunications work evolved toward network engineering, equipment maintenance, and other specialized responsibilities.

The human connection disappeared from one part of the process, but the larger communication system continued to grow.

10. The Professional Typist

Typing is now considered an ordinary office skill, but there was a time when producing a clean, professional document required specialized training and dedicated workers.

Professional typists used typewriters to prepare letters, reports, manuscripts, forms, and business documents.

A typewriter offered no convenient undo button. An error could require correction fluid, careful overwriting, or retyping an entire page. Carbon paper could be used to produce copies, but mistakes might appear on multiple sheets.

Accuracy and speed mattered.

Businesses, government offices, publishing operations, and other organizations needed people who could turn handwritten notes or dictated words into readable documents.

The profession required more than the ability to press keys. Typists needed familiarity with punctuation, spelling, document layout, and the conventions of professional correspondence.

Today, almost anyone with a computer can produce a document. Word processors offer spell-checking, formatting tools, templates, and straightforward revision.

Speech-recognition systems can even convert spoken words into text.

But the work of producing accurate documents has not vanished. It has been redistributed among administrative professionals, editors, writers, assistants, and people who create and maintain digital content.

The professional typist’s story illustrates an important principle: a skill can become so widely accessible that it stops defining a separate occupation.

That does not mean the original skill has lost all value. It means the surrounding technology has changed the threshold for performing it.

11. The Human Lighthouse Keeper

For generations, lighthouses helped mariners identify coastlines, avoid dangerous waters, and navigate around hazards.

Behind many of these structures were lighthouse keepers, responsible for maintaining the light and ensuring that its supporting equipment continued to function.

Depending on the lighthouse and historical period, the work could include tending lamps, maintaining fuel supplies, cleaning lenses, winding mechanisms, recording observations, and keeping the building in working order.

Some lighthouse stations were isolated, exposed to harsh weather, and difficult to reach.

A keeper might have to remain attentive to equipment while living far from major settlements. The position required reliability, practical knowledge, and a willingness to work under conditions that could be uncomfortable or lonely.

Modern navigation benefits from automated lighthouse equipment, remote monitoring, satellite positioning, electronic charts, and other technologies.

Many traditional lighthouse-keeping duties have consequently been reduced or automated, although lighthouses and other navigational aids remain important in various locations.

The surprising part is how much responsibility could once be concentrated in a single person’s routine.

A lighthouse was a physical structure, but it also represented a promise: a light would be visible when sailors needed it.

Someone had to make that promise reliable.

Today, automation can keep the light operating with less direct intervention. But the original objective remains unchanged.

We have not stopped needing navigational safety. We have developed more sophisticated ways to provide it.

12. The Human Type Setter

Before desktop publishing and digital printing, producing a printed page required extensive physical preparation.

Traditional typesetters arranged individual pieces of metal type into lines and pages. Each piece represented a character, punctuation mark, or other printing element.

The process required considerable precision. Letters had to appear in the correct order, spaces had to be balanced, and the completed arrangement had to be suitable for printing.

A newspaper page was not simply a file sent to a printer. It was the result of physical objects being arranged into a carefully structured composition.

The work demanded familiarity with typography, spacing, layout, and the practical details of printing.

Imagine discovering a spelling mistake after arranging an entire page of tiny metal characters. Correcting the error could require carefully removing and replacing individual pieces without disturbing the surrounding layout.

Now compare that with editing a word in a digital document.

The transformation is extraordinary.

Modern publishing software allows designers to change fonts, resize headlines, rearrange paragraphs, and correct errors without physically rebuilding a page from thousands of individual pieces.

Yet the underlying principles of typography remain recognizable. Readability, hierarchy, spacing, and visual balance continue to influence how people design books, websites, newspapers, and mobile applications.

Traditional typesetting is a useful reminder that many digital tools are built around concepts that existed long before computers.

The interface changed. The medium changed. The fundamental challenge of arranging information clearly remained.

13. The Rat Catcher

Before modern pest-control methods and improved urban sanitation became widespread, rats could create serious problems in homes, warehouses, farms, and food-storage facilities.

They could damage property, contaminate stored food, and contribute to the spread of certain diseases.

As a result, some communities employed rat catchers or relied on people who specialized in controlling rodent populations.

These workers used various methods, which differed according to the period and location. Their work could involve traps, trained animals, and practical knowledge of rodent behavior.

A successful rat catcher needed to recognize signs of infestation, understand where rodents traveled, and determine how to reduce their numbers.

The occupation might sound like an unusual career choice today, but it addressed a real problem.

Modern pest-control professionals continue to perform related work using improved monitoring techniques, exclusion methods, sanitation practices, and carefully selected control measures.

The historical occupation therefore has not disappeared entirely. Instead, it has evolved into a more formalized field that can involve building inspections, risk assessment, environmental management, and integrated pest control.

There is also a broader lesson here: jobs that sound strange when removed from their original context often become perfectly understandable once we examine the problem they were designed to solve.

A rat catcher was not simply someone who disliked rats. The occupation existed because rodent control was an important part of protecting food supplies and maintaining habitable spaces.

14. The Professional Ice Delivery Worker

Ice cutting and ice delivery were closely connected, but they represented different parts of the historical refrigeration business.

Once natural ice had been harvested and stored, someone needed to transport it to customers.

In cities where households and businesses used iceboxes, delivery workers carried blocks of ice along established routes. Customers could order specific quantities, and workers supplied the material needed to keep their food-storage cabinets cool.

Some iceboxes had a compartment for a block of ice and a separate space for food. As the ice melted, the cooling effect helped preserve the contents for a limited period.

The delivery worker was therefore part of a household’s basic food-preservation system.

Imagine ordering refrigeration supplies in the morning and expecting someone to carry a heavy block of frozen water into your home.

Modern consumers rarely think about where the cold inside a refrigerator comes from. Electricity powers a system that removes heat, allowing the appliance to maintain a cool interior.

The old arrangement depended on a physical commodity that had to be harvested, stored, transported, and replenished.

The delivery route itself could require planning. Workers had to serve customers efficiently while managing a product that melted and became heavier or more difficult to handle when wet.

The occupation gradually lost much of its importance as mechanical refrigeration became widely available.

But it represents something larger than the disappearance of a delivery job. It shows how a change in technology can reorganize the relationship between households and essential resources.

A family once depended on a delivery schedule to keep an icebox working. Today, a refrigerator can operate continuously as long as it has the necessary power and remains in working condition.

The service moved from a recurring physical delivery to an appliance that performs its task inside the home.

15. The Human Bookkeeper Who Calculated Everything by Hand

Before computerized accounting systems, businesses relied on ledgers, handwritten records, calculating machines, and carefully maintained financial documents.

Bookkeepers recorded transactions, tracked payments, reconciled accounts, and helped ensure that the numbers in a business’s records made sense.

The work could be repetitive, but it required discipline and accuracy. A missing entry or arithmetic error could create confusion that took considerable time to resolve.

Businesses needed reliable records to understand what they owned, what they owed, and whether their operations were financially sustainable.

Some bookkeepers used mechanical adding machines and other devices, but much of the process still depended on people entering information and checking calculations.

Today, accounting software can automatically total transactions, categorize entries, generate reports, and connect records from multiple systems.

That does not eliminate the need for sound financial judgment. People still need to investigate unusual transactions, interpret financial information, maintain controls, and ensure that records are accurate.

The historical bookkeeper would recognize much of the logic behind a modern spreadsheet, even if the interface looked completely unfamiliar.

Rows, columns, totals, balances, and reconciliation are not inventions of the digital age. They are ways of organizing information that existed long before modern computing.

What changed was the speed and scale at which those operations could be performed.

A person who once spent hours checking calculations might now use software to complete them in seconds and devote more time to understanding what the results mean.

The occupation demonstrates that automation does not always remove the purpose of a job. Sometimes it removes the repetitive part and makes the remaining work more analytical.

What These Strange Jobs Tell Us About the Future

Looking back at these occupations, a pattern begins to emerge.

The world changes, but human needs tend to persist.

People still need to communicate, navigate, preserve food, maintain public spaces, manage money, and organize information. What changes is the infrastructure surrounding those needs.

The knocker-upper became unnecessary as reliable alarm clocks became widely available. The lamplighter’s routine was transformed by electrical lighting. Traditional typesetting gave way to digital publishing. Manual telephone switching was largely replaced by automated networks.

In each case, technology changed the relationship between the task, the worker, and the person receiving the service.

But history rarely follows a perfectly straight line.

Some jobs disappear almost entirely. Others survive in specialized forms. New occupations emerge around the systems that replace older ones.

The disappearance of natural-ice delivery, for example, did not eliminate the need for refrigeration. It helped shift work toward manufacturing appliances, maintaining cooling systems, managing electrical infrastructure, and developing more efficient technologies.

Likewise, digital publishing did not eliminate the need to arrange information on a page. It created new opportunities for graphic designers, interface designers, digital publishers, and software developers.

A task that once required a dedicated worker may eventually become a feature inside a machine.

That is one of the most interesting ideas in the history of employment: an occupation can disappear while the problem it solved remains important.

This is also why predicting the future of work is difficult.

A modern occupation may appear permanent because it is familiar. We see people performing it every day, and we assume its current form will continue indefinitely.

But the people who worked as ice cutters, town criers, and professional typists probably had their own reasons to believe their occupations would remain useful.

They were solving real problems. Their jobs made sense within the systems of their time.

Then the systems changed.

Consider some of the work that seems ordinary today: manually entering data, sorting documents, answering routine questions, transferring information between applications, and preparing standard reports.

Could some of these tasks become as unfamiliar to future generations as delivering blocks of ice?

It is possible. Software and automation are already changing how many routine activities are performed. However, the precise occupations that will grow, shrink, or emerge are difficult to predict, and technological change does not automatically eliminate every job associated with an affected task.

The more useful question may be this: which human needs will remain, and how might the methods of meeting them change?

The historical record suggests that adaptability matters because the tools people use are never guaranteed to remain the same.

It also suggests that today’s ordinary skills can become tomorrow’s specialized knowledge—or disappear into systems that make their operation almost invisible.

The Past Was Not Strange to the People Living in It

There is a temptation to look at historical occupations and laugh at how complicated everyday life once appeared.

Why would anyone pay another person to wake them up? Why would an entire business depend on delivering frozen water? Why would a city need someone to walk through its streets announcing information?

The answer is simple: those jobs existed because they made sense in the world that created them.

People did not wake up one morning and decide that their society needed unnecessary complications. They developed practical solutions using the resources and technology available to them.

Sometimes those solutions became entire professions.

The people who performed these jobs were not merely participants in history. They were part of the process through which societies learned to organize work, distribute services, and solve recurring problems.

Their occupations tell us what was difficult, what was valuable, and what people were willing to pay someone else to do.

They also reveal how much of modern convenience depends on infrastructure that we rarely notice.

When you switch on a light, make a telephone call, preserve food, or edit a document, you are benefiting from systems built through generations of experimentation and improvement.

You do not need a lamplighter because electricity and automated lighting have changed the task. You do not need an ice delivery worker because mechanical refrigeration has changed the process. You do not need a human switchboard operator for most ordinary telephone calls because communication networks can establish connections automatically.

The inconvenience has not always vanished. Often, it has simply moved somewhere else in the system.

Behind a modern refrigerator are engineers, manufacturers, energy networks, and maintenance workers. Behind digital communication are cables, wireless networks, servers, software, and people who keep the infrastructure functioning.

Technology can make a process feel effortless without making the process itself simple.

Perhaps that is the most surprising lesson hidden inside these strange historical jobs.

The future will probably produce occupations that sound equally ridiculous to us today. People may eventually struggle to understand why someone was paid to perform a task that a small device or an ordinary piece of software can handle automatically.

They may find our current routines unnecessarily complicated. They may wonder why we spent so much time moving information between applications, manually checking documents, or repeating the same actions every day.

And somewhere in the future, someone may write an article about the strange jobs people once did in the twenty-first century.

The details will be different, but the underlying story will remain familiar.

Human beings encounter problems. They invent solutions. Those solutions become work. Eventually, new inventions transform the work itself.

Today’s ordinary job is not necessarily tomorrow’s permanent occupation. Sometimes, it is simply a temporary answer to a problem that humanity has not yet learned to solve differently.
