M: I enjoyed your lecture today, Dr. Beech. See you.
W: Goodbye. Oh, Jack?
M: Yes, Professor?
W: Have you got a minute?
M: Uh... sure. Have I done something?
W: No, Jack. Not at all. You’re doing very well indeed in my class, and, uh, I’ve noticed that you seem particularly interested in my research...
M: Thanks! Yes. It seems like fun to be working with primates. They’re very likeable animals, aren’t they?
W: Yes, they are. But they do take a lot of, well, looking after to keep them healthy and happy. I’ve got an assistant, Larry--you know him?
M: Oh, yes, I know Larry, Larry Easton.
W: Yes, that’s right. And he’s graduating in June. So I was wondering if you might be interested in, uh, taking over for him, taking his assistantship.
M: Oh! Uh. Yes. Yes! That’s something I would really like to do,yes.But,uh... I guess I should find out a little bit more about it. I mean, the hours, the time involved, and can I do the work?
W: Well. Have you got a little time right now? Shall we have a talk?
M: Uh, yes. my next class’s not till one. Sure.
W: Good. My research assistant is mostly in charge of maintaining the laboratory animals --preparing their food, cleaning their quarters, uh, feeding and watering them, of course, and, uh, just keeping an eye on things, you know--making sure they’re healthy and comfortable.
M: How many primates do you have in the lab?
W: Twelve right now.
M: Well, it sounds fine, I suppose. What do they eat? Fruit?
W: Yes, fruits, mostly --apples, grapes, pears --and also some vegetables. Lettuce, uh, carrots... we try different things sometimes. And they get mealworms for snacks. Larry’ll show you how to do it.
M: What kind of hours are we talking about, Professor?
W: Well, student assistantships are limited to fifteen hours a week --university regulations. The animals have to be tended every day, of course, but I’ll be responsible for Sundays and holidays. Would you be able to do that?
M: Sure, that sounds fine. My class load’s not so heavy now that I’m in third year. Oh. Uh... can I ask how much it pays?
W: Oh! Sorry, Jack. Of course! Fifteen dollars an hour, $225 a week. The university will withhold some for taxes and issue you a check at the end of each month. It should be for about $850, I think.
M: Great. That’ll help me out a lot with my expenses.
W: OK. Then I’ll talk to Larry, and we’ll see when we can get together, the three of us, and set up some time for you to start learning the routine.
M: Thanks very much, Professor. Thank you for thinking of me.
W: And thank you, Jack. I know I’ll be able to rely on you. See you.
M: See you.
