Moose Attack!

Oooh, I totally kicked off at Fred in Russian today, absolutely without meaning too - but now I'm kind of glad I did.
Not sure if I've mentioned Fred on here before, so here's the lowdown: He's in nearly all of my Russian and German classes, so I see him every single day. Not that I understand why he's at University, because he patently knows everything already. He already has GCSE Russian, so he makes the rest of us look pretty stupid - but he does the same in German even though we all have A-Level. He speaks about a dozen other languages too. And he isn't subtle about it. If you get something wrong, he will laugh at you unashamedly, and he often corrects the teachers, even when they're right.
So anyhoo, today we were in our Russian Oral class and Svetlana (lecturer) asked me a question. Now, I knew the answer to the question. I often know the answer to the question, but it all goes wrong when it comes out of my mouth - which is what happened today. I can't remember what I said wrong, but Fred burst out laughing. Since I was quite pissed off anyway, I couldn't stop myself from yelling at him about how I didn't like being laughed at and found it offensive. The look on his face was priceless. He may not talk to me again, ever - but so what?
Still feeling quite grumpy about things generally, but maybe now Fred will think twice before laughing at other people's mistakes.
