W: Hello?
M: Hello, Linda?
W: Hello, Abruzzi.
M: Look, what are you doing on Tuesday night? There is a great show at the Grand Theater.
W: Tuesday night? Oh, sorry, I’m planning to finish my term paper. It has to be in on Wednesday morning.
M: Oh well, never mind. Look, Wednesday, why don’t we go out for dinner? Just you and me, very nice and romantic. We could go to that little restaurant you like so much.
W: Sounds like a great idea, but I think I might have to help my roommate clean up the apartment. You see, we are having some people in on Wednesday night, so we want the place; to look really nice.
M: Well, that means you’re going to be busy Wednesday night too.
W: I’m afraid so.
M: Well, how about Thursday night? There’s going to be a football championship at school. How about we go and root for the Old Blues?
W: Yes, I was planning to see that, but you know what’s come up—it’s my mama’s birthday, so we are taking her out for dinner.
M: Well, I suppose you’re busy on Friday night, too. I had planned to invite you to a concert.
W: Well, I was going to stay in, with all these late nights. But since I’ve been tied up all week, sure, I’d love to go to the concert with you. What time is it?
