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!
