M: Morning, Myra.
W: Oh hi, Arthur! You’re taking Ecology 311, too?
M: Looks like it. It’s my only elective course this term.
W: Really? What happened?
M: Oh, I just took too many my second year and now I’ve got to pick up all the required courses I’ve been ignoring. University’s just too much fun, I guess. And it has helped me decide my major, finally.
W: What’s it?
M: I’m going for my BA in business administration.
W: So, why 311? An ecology course isn’t going to help you in your office job at some corporation.
M: Probably not, but... it still seems interesting--and important. We all need to know about the environment, no matter what we do for a living.
W: Yeah, you’re right. And maybe you will be able to use it. Maybe you’ll end up working for a green company or something.
M: Could be. There’s more and more of those every day. Is that why you’re taking this?
W: Well, it’s not an elective for me. I need 311 for my BS program. We need several cross-field courses to "broaden our understanding", and this is one of them. Actually, though, I’m looking forward to this course: "Nature’s Influence on Man--Man’s Influence on Nature"! Sounds like a really useful topic, doesn’t it? And Dr. Forsythe is supposed to be a very engaging lecturer.
M: Yeah. Sure.
W: Did you pick up your textbook yet?
M: No. I’ve been looking for a secondhand copy before I spring for a new one. It’s expensive--forty-five bucks!
W: They all are, aren’t they? Why do poor college students have to pay so much for their textbooks? It ain’t fair.
M: It’s just economics. Nobody reads them except the students that take the courses. The publishers probably didn’t print more than a few hundred copies of our text, you know.
W: I suppose you’re right. Where you gonna find a used copy? At the bookstore?
M: They don’t have any there now-- I checked. I put up some notes on the Science Building bulletin boards yesterday. Maybe someone there’s got one they don’t want to keep anymore.
W: Well, uh, if you hear about two of them, will you let me know? I’d like to save a little money, too.
M: Sure. If I do, I’ll buy it for you and you can pay me back. How much are you willing to pay?
W: Oh, anything under thirty-five dollars will be fine. A penny saved is a penny earned. But if you haven’t found one by next Monday, I’ll have to buy a new one then, so email me Sunday night either way, will you?
M: You bet. Oops! It’s almost 8:00. Here comes Dr. Forsythe.
