Girl: Life must have been difficult when you were a kid.

Woman: Of course we did! How old do you think I am? The telephone was invented in 1876.
Girl: How about cars? I bet cars weren’t invented yet.
Woman: Sure they were. Cars were invented in 1885. My family had a car. I think you need to take a history class, Alice.
Girl: Ha, ha! Well, did you have a TV?
Woman: No, we didn’t. The TV was invented around 1927, I think. Some friends of mine had one. But in those days, TVs were really expensive, and we couldn’t afford one.
Girl: And I bet you didn’t have calculators and computers and stuff. That’s something I do know. We learned in school that hand-held calculator were invented in 1971 and personal computers were invented in 1976.
Woman: You’re right. I didn’t have those things when I was young. But I do now!
