I was ten years old in 1977.
Teens would spend hours on the phone, to the annoyance of their parents.
Making a “long distance” phone call was expensive. If you had to make one, you kept the conversation short.
If you lived in a northern state, your car wouldn’t start half the time in the winter. You would have to pop the hood and fiddle with the choke in order to get it to start.
It seemed everyone smoked cigarettes.
Traveling on a plane was considered luxurious. Only “rich” people flew.
Everyone got the newspaper.
Offices were very noisy, with women tapping away on typewriters.
Dictionaries and encyclopedias were commonplace.
Virtually no one carried a gun. (Well, except for criminals.) Legal concealed carry wasn’t a thing.
Cashiers had to enter the price of each item by hand. After a while they didn’t even have to look at the price tag; they knew the price of each item in the store. (Worked well until there was a price change.) Baggers put your groceries in paper bags and loaded them in your car.
No craft beer. And beer commercials were commonplace on TV. Collecting beer cans was a fun hobby for teens.
Driving to a new place? You used a paper map.
Soda/pop was sold in glass bottles, and you returned the (empty) bottles to the store. In many states the store paid you for each returned bottle. (In Ohio it was 10 cents per bottle.) Children would often go to construction sites with a wagon, collect discarded pop bottles, and then return them to the store for money.
Hitchhiking was commonplace.
People wore wrist watches.
Television sets were very expensive and very unreliable. Every town had a TV repair shop. When your TV wasn’t working right, you would call the “TV repair man.” He would come to your house and spend an hour or two working on your TV, replacing tubes, etc. These visits were not cheap.
