Mate, that's the whole point of Fresher's Week. NO ONE knows anyone else, when you're a fresher you're totally new, and so is everyone else, the various activities throughout the week help you to make friends. You could give it a miss, but by the time lectures get started other people will have already made friends and formed groups because they actually socialised instead of staying at home and playing Halo...your call.
lol, no need to try and put an ultimatum on me. I'll go with friends from outside of Uni, see what the potential is like and then make up my mind for the future. It's just that its too far from where I live so i'd rather rather continue my local social life then attempt to create a potentially unsuccesful one in Uni with people I don't like but trying to force myself to.
