A：I think I'm going to go home.
B：Why? We just got here.
A：I know, but it's 12:45 a.m. It's pretty late.
B：Twelve thirty a.m. isn't late! This party will probably go until three or four o'clock. C'mon, don't leave yet!
A：Three or four o'clock?
B：Sure.
A：I never stay out that late. That's too late.
B：But it's Saturday night. We have nothing to do tomorrow. Why not stay out?
A：Were you so wild when you were in Los Angeles，Robert?
B：Yes, I was. People know how to party here. In LA, some people know how to party. But here, everyone does. Do you want to smoke?
A：I don't want to.
B：That's alright. But I think you need another drink. People will probably start dancing soon.
A：I wonder if I can drink more. I already had three beers.
B：C'mon, Ann, you are in an American university now! You have to learn how to enjoy American life.
A：But a university is for studying.
B：That's true. We study hard all week. And then, on the weekend, we party hard. That's the best way to live. Remember? To be is to do and to play.
A：Alright. Another drink, please.
