M: What do you think of Professor Potter’s course, Jane?
W: Not much.
M: Why, what’s wrong with it?
W: Oh, I don’t know.  It’s just that he overloads it with details. That course he gave on town planning last year. It was just the same load of details, which you could have got from a book anyway. There was no overall...
M: No general overview you mean?
W: Yes. I suppose you could call it that. I couldn’t see the town for the buildings.
M: But you’ve got to have details in this kind of subject. Anyway I think he’s good. You take his first lecture for instance. I thought that was very interesting, and not at all over-detailed.
W: Well, he starts off all right, but then he just piles on the details.
M: Now you’re exaggerating.
W: Well, the way he dealt with the western developments, that wasn’t bad, I suppose.
M: You seem to have got something. Perhaps Potter is a little disorganized, but I think he’s good.
W: Do you really think so?
M: He does do most of his teaching to the postgraduates. He only does the one undergraduate course each year. After all, I think he tends to forget where he is. He starts off being nice and general and then tries to cram in a bit too much specialized information.
W: The main thing I object to is this lack of direction.
