| Father: For the last time, you cannot have your ears pierced. I don't want to talk about it 1 . Son: But, Dad, all the other guys (哥们儿)… Father: I don't care about"all the other guys." I don't care 2 they do or don't do. That's up to them and their 3 . I care about you. And you cannot have your ears pierced (make a hole in one's ear), and that's 4 . The subject is closed. Now go do your homework. Son: But, Dad, I just want to have 5 ear pierced. Father: That's the most ridiculous thing I have ever heard of! Piercing just 6 ! That's crazy! People will 7 you're crazy! I think you've lost your mind. Son: It's not crazy. It's the style (风格), Dad. All the guys have just one ear pierced. That's the 8 it's done. It's cool, Dad. Sometimes they have three or four holes in one ear ― 9 in just one ear. It looks great! I want to be in style. I want to be like the other guys. Father: Stop here. Just 10 it ― and go do your homework. If you spent as much time thinking about math as you do about earrings, you would be at the top of your class. | ||||
