Brother : Hey, Sally! Are you going to stay in that bathroom for the rest of your life?
Sister : (From the bathroom) Come on, I just got in here.
Brother : You're kidding me. You've been in there for two hours twenty-four minutes and fifteen seconds.
Sister : All right! Five more minutes, OK?
Brother : What're you doing in there?
Sister : (Coming out from the bathroom) Taking a bath. What do you do in a bathroom? Get a sun tan?
Brother : A bath for two and a half hours?
Sister : What's wrong with that? I'm going out with Daniel tonight.
Brother : You what? No way! Mom doesn't let you go out on dates. Everybody knows that.
Sister : Yes, she does: She said I was old enough to make decisions.
Brother : That's a quick change.
Sister : Do I look good in red? Or maybe black?
Brother : No, you look awful in either red or black. I think white is better.
Sister : Is that so?...I better ask Mom for opinions. Are you free tonight?
Brother : Yeah....No, you're not going to use my car.
Sister : Come on, this is my first time going out on a date. I'll give you Stella's telephone number in exchange.
Brother : That's a deal.
