Alice: Was your life very difficult when you were a kid?
Grandma: Oh, not really. Why?
Alice: Well, you didn’t have modern inventions like a telephone, right?
Grandma: Of course we did! How old do you think I am? The telephone was invented in 1876. You need to take a history class, Alice!
Alice: Haha! How about cars? They weren’t invented yet, were they?
Grandma: Yes, they were. Cars were invented in 1885. My family had a car.
Alice: Well, did you have a TV?
Grandma: No, we couldn’t afford one. They were expensive in those days. The TV was invented around 1927, I think.
Alice: Well, I know that you didn’t have a computer because we learned in school that personal computers were invented in 1971.
Grandma: You’re right. But I have one now!
