KAREN: I'm not comfortable about this, Sandy.I don't understand most of these games. SANDY: That's okay. I can explain a little. KAREN: I don't want to lose all my money. SANDY: Don't worry. You can't lose all your money.because you won't gamble all your money. KAREN: I guess you're right. SANDY: Of course I'm right. I already told you the rule for Las Vegas. Remember? KAREN: Yes, I remember.You must decide how much money you will gamble before you start to play. SANDY: That's right. That's the best way to have control over yourself.You say to yourself. "Tonight I will gamble fifty dollars. Only fifty dollars. No more."If you follow the rule, you can't lose more than fifty dollars. KAREN: I know it's true, Sandy. But still some people lose control.They start to gamble, and they can't stop. SANDY: But I won't let you do that. I will watch you. KAREN: Okay. SANDY: So how much do you want to gamble? KAREN: Maybe 500 dollars. SANDY: 500 dollars! That's too much!You just said you are afraid to lose your money.If you're afraid, why do you want to gamble 500 dollars? KAREN: I don't want people to think I'm stingy. SANDY: That is a bad attitude to have, Karen!If you think that way, Las Vegas will be really dangerous for you. KAREN: So how much should I gamble? SANDY: Why not fifty or one-hundred dollars? KAREN: Okay. One-hundred then. Do you think I will lose it? SANDY: I don't know. You have to be smart, but you have to be lucky too.Some games are all luck. With some, you need to be smart. KAREN: I want games that are all luck. SANDY: I knew you would say that! Then you should play the slot machines. KAREN: Slot machines? No, I don't want that! That's too boring.I want a game with cards or dice. SANDY: So what do you want to play then? KAREN: Blackjack.We can play blackjack. And I will gamble one-hundred, or maybe two-hundred dollars. SANDY: Huh? You are breaking our rule already! And we didn't even start to play yet! KAREN: Oh, don't be so strict! We are in Las Vegas. SANDY: Yes, and if I stay with you, we will have to walk back home to New York.Because we will lose all our money and our plane tickets too!
