M: Let’s go swimming over at the student center.
W: I’d like to, but I have a paper due on Friday, and I haven’t even started it yet.
M: Just an hour. I’ve got a test tomorrow, so I won’t be able to stay very long.
W: I need the exercise, but l just can’t spare the time.
M: Okay. How about dinner at the Grill? You have to eat sometime, and it’s right by the library. I’ll go over there with you after dinner, and you call do your research while I study for my test.
W: Well.
M: Come on. You’ll probably want to stay late, and you shouldn’t walk home after dark. I’ll stay until you’re ready to go.
W: That would be nice, but...
M: Look, we really wouldn’t be wasting any time. We’d just be doing everything we need to do, but we’d be doing it together. I just want to spend time with you.
W: Me, too. Okay. I need to go home first, then I’ll meet you at the Grill about six. Is that all right?
M: That’s great. We’ll get everything done. You’ll see.
