when you were a kid.
Woman: Oh, not really. Why do you say that?
Alice: Well, you didn’t have many
modern inventions. Like, you
probably didn’t have a telephone,
right?
Woman: Of course we did! How old do you
think I am? The telephone was
invented in 1876.Alice: 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.
Alice: 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. Alice: 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 calculators were invented
in 1971 and personal computers
were invented in 1976.
Woman: You are right. I didn’t have those
things when I was young. But I do
now!
