I live on a boarding house during the week, mainly so I can be around people other than just my family. I live in the middle of nowhere and can't drive, so meeting up with people is difficult without getting a lift.

99% of the people I board with are great people. I have a laugh and a joke with them, they come from all over the world (mainly Eastern Europe and China) so there's always something going on. It would be typical that the 1% I don't get on with comes from the same country I do (England).

It's one guy, he sees himself as the self-proclaimed leader (mainly because he failed his final year and has to repeat it, so he's been here longer than the rest of us). He's also bigger and stronger than I am physically, he looks obese but underneath it there is muscle on more muscle. So he chooses to wind up anyone that he thinks won't stand up to him. He's tried to start something with me and a few select others on loads of occasions, but never on anyone who would be able to put him out. Some might call that playing it smart, I call it cowardice.

Anyway, this week I had enough of the constant insults. I was on lock up, so I locked him in the computer suite. Everyone, including those he wouldn't pick on found it hilarious. I saw it as justice. I might not be able to touch him in a fight, but there is more than one way to skin a cat, right? When he got out he emptied a pan of water over my bed and pissed on the clothes in my wardrobe. So I grabbed a cricket bat and ran after him. Consider the fact that I'm around 5'3" at a push and he's above average height (he's 19), I must have looked ridiculous. I scared my room mate enough for him to run to get one of the Polish guys (who are VERY capable of sorting this guy out). I laughed when they said they were there for the other guy's protection, but whatever - argued in the corridor and they managed to talk me down. I went back to my room, talked it out with my room mate and went to sleep.

Now considering what this guy did, I don't want to see him again. And if I have to see him, I sure as hell don't want to talk to him. But he's started hanging around with my friends more often now. Taking over conversations, knowing that I don't want to be a part of anything he's involved with. My friends heard about everything and I'm not worried about losing them, he's already been shot down once when he tried it before. I just don't want the urge to dive over a table and beat the shit out of him every time I'm with my friends. There is a party this weekend and we're both going to be there. And when he has a drink he's going to try and start a fight. I'm not scared of getting hurt, I already know that there are more people than he realises that are aching for a reason to beat down on him. I just don't want it to get to that stage in the first place.

So, any advice?
