W: I haven’t seen you here for a couple of weeks. Have you stopped eating or something?
M: No. Does it look as if I’ve stopped eating? I’ve been spending a lot of time in the library.
W: Working on a paper?
M: I wish I were working on a paper. I was working on three different papers: anthropology, English literature, and history.
W: Wow. That is a lot of work.
M: Yeah. And what’s frustrating is that I’m studying 19th century British Empire in all three classes. But I can’t write a single paper for all the three.
W: Why not?
M: The professors won’t let me. Even if I make it three times as long as the suggested length.
W: Oh. That’s too bad. Could you write your paper on three aspects of one topic? M: Mm. What do you mean? Do you have something in mind? W: Well, let’s see. Maybe you could do something with Romanticism, like—write your anthropology paper on the cultural basis of Romanticism; and your history paper on the influence of the Romantic poets on the British foreign policy; and... OK... and your English paper on analysis of some Romantic poems.
M: Hey. That’s not a bad idea. I’ve already started the research for one of my papers. So I can use that. Oh, it’s so nice! What can I do to repay you?
W: You want to wrap up my chemistry lab for me?
M: I’d love to. But I’ve never taken chemistry. So I’m not sure if you will like the results.
W: Oh, well. No thanks necessary then. Have a good weekend. And try to get out of the library and get some sleep. You look tired. You have big circles under your eyes.
M: OK. I’ll try. See you later.
W: See you.
