Okay, I'm done.

I have this one student. Let's call her Ophelia. Ophelia has spent the ENTIRE semester pissing and moaning about how HARD everything is, how much WORK everything is. She's VERY vocal and uses a tone of voice I interpret as borderline rude.

Well, she stops me before I start class today: "I don't understand the calculations from lab! I can't do the lab!"

So I sigh. And I say, okay, let me finish the chapter we're working on and I'll go over the calculations again for you and for anyone who needs them.

So I do that. Look out over the class. A number of students have their calculators out and are taking notes. Ophelia? She's talking with her boyfriend/the guy next to her she flirts with in class (I'm not sure which: I don't care to enter that much in the personal lives of students).

You know what? I'm done. If she gripes again that she can't do the lab calculations, I'm going to mention that I noticed she was talking with Fortinbras next to her during the entire time I was going over stuff, and that that's not cool. And I'm going to tell her (in more polite terms of course) that she can suck it, because I put myself behind in class FOR HER and she apparently couldn't be arsed to pay attention. So whatever.
