M: Hello, Hilltop High School.
W: Hello, is that Mr. Andrews?
M: Yes, Who’s that? Can I help you?
W: This is Karen Wilson. Joe is my son, and you teach him this year. Perhaps you can explain why Joe got only 45.
M: I’ll do my best, Mrs. Wilson. Did Joe have anything to say about his low grade?
W: Only that he’s finding math very difficult to understand this year.
M: I understand how he could feel that way.
W: The problem is not that. Joe has never done badly in math before.
M: And I would certainly like to help him do better. Do you have any suggestions?
W: Not really. Do you?
M: Well, it would be very helpful if you could make sure Joe does his homework.
W: Hasn’t he been doing it?
M: Not always.
W: I see. OK, I’ll make sure he does it.
M: Great.
