M: Come in, come in! What can I do for you?
W: Prof. Donner, are you giving your Advanced Geology course again next semester?
M: Yes, I’m planning on it.
W: I wonder if I could enroll in it. I know it’s a graduate course and I’m only a junior, but...
M: Aren’t you a bit young? I’ve allowed qualified seniors to take the course and they usually have a hard time keeping up.
W: I know, but the geology of the American West is my favorite interest and I’ve done a lot of reading in the field. Last semester I took Prof. Burman’s course and I didn’t find it nearly challenging enough.
M: I see. You certainly aren’t one of those students who are out for easy grades.
W: I should say not. I really want to learn something.
M: Well, I’ll speak to Prof. Burman, if he thinks you’re ready, I’ll let you enroll.
W: Oh, thanks. Professor Donner, that’s really very nice of you.
