A: Do you know anything about Dr. Miller's classes? B: Yes. Are you in his class? A: I'm thinking of taking his class next semester. B: He really knew his stuff, but he graded hard. Would that be OK? A: Yes, I really need someone who is really good. B: I didn't find it overwhelming to earn a good grade if you work at it. Can you do that? A: Maybe, but I'm not sure. B: Man, this guy was so funny when he was teaching. I like that, don't you? A: No, that stuff isn't important to me. B: Did you know that he is a fairly new teacher and very current in his field? A: I don't care about any of that. B: We all are looking for different things in an instructor. I hope I've helped you.
