bother-ing, me

I just got off the phone with my Mom who asked about how my comps were going; what I was reading, etc. When I started talking about it, she cut me off in the middle of my explanation to ask another question about something else entirely. And then hurriedly got off the phone. Maybe she got caught up with something. This time. But it happens practically every time I talk about school. Why does she ask me if she doesn't want to know? Am I supposed to say, "Everything's great." And leave it at that, even if it isn't true?

Why bother? Why do I bother?
