A: Could I invite my friends to a party on Saturday, Mom?
B: Of course! That sounds like fun.
A: Yeah. Ummm, could I borrow some money?
B: What for?
A: I need to buy some drinks and snacks. Could I go to the store?
B: Well, I'm going to tomorrow, and I can buy some drinks and snacks for you.
A: Oh, good. Thanks mom.
B: You're welcome. Oh, could you clean your room?
A: I cleaned it last week.
B: You need to clean it again for your party.
A: OK. At the party, could I use your CD player?
B: Yes, if you're careful with it.
A: Don't worry, mom.
B: Now, there are a few other things I want you to do before the party. Could you move the good chairs to the bedroom, and clean the living room?
A: Sure. Dave is coming early on Saturday, so he can help me.
