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!
