W: Hi, Kaven. Your roommate told me that I could find you in the TV lounge. What are you doing here?
M: What does it look like I am doing?
W: Well, it looks like you are watching television, but we have a linear algebra mid-term tomorrow, so I thought you’d be studying for it and maybe I can study with you.
M: Oh, well, I was just taking a break. This linear algebra stuff gives me a headache if I work on it too long.
W: I know what you mean. I’ve been working on it for three hours already. I’m beginning to go cross. I’d been thinking at the sample problems. I just don’t get some of them.
M: But I can’t believe you are coming to me. I mean you do know what I got on the last test, don’t you?
W: Yeah, I know. You told me. I just thought two heads might be better than one.
M: Yeah, that’s a nice idea. But… you know, I wish I knew that person in our class who got a hundred on the last test. She didn’t miss a question. Umm… was it Elizabeth?

W: Yeah, I guess you are right. But you know what? She owes me a big favor. Let’s at least give her a call and see what she says. Maybe going over some of the problems with us would help her review the material.
M: It’s worth a try.
