M: Pauline, I heard you're going back to Australia pretty soon.
W: That's right, David. And I'm really busy these days!
M: I can imagine. But listen... I'd like to get together with you before you go. Would you like to go out for dinner one night?
W: That's a great idea. Let me see... Monday night is not good. I have to study for that final exam.
M: Me, too, but I'm free on Tuesday. How about going out that night?
W: I'm afraid I can't. I'm going out for dinner with Nancy at 6: 30.
M: Are you going to the last class party on Friday night? Let's go out for dinner before the party. It doesn't start until 8:00.
W: I know, but there's a lot of preparation work, so we can't go out before that. I love to eat, but I have to help with the preparation work.
M: You are right, but...
W: Wel1, there's always Saturday night. Are you busy then?
M: No... Saturday I'm free.
W: I'm going to a disco with a group of friends. Do you want to join us?
M: I'd really like to have a quiet dinner instead. Oh! Can I call you back? Someone's at the door.
W: Sure. I'll be home all afternoon.
