I started an AAT Accounting course on Monday and I was hoping because it's a vocational study sort of, that I wouldn't have to faff around with group work and "confidence building tasks". I simply want to go in, learn, discuss if need be, sit my exams and progress onwards. I don't want to make little buddy buddy friends along the way I have a girlfriend, family, and close friends already.
There are several older adults on the course, I enjoy sitting near them because they generally won't mix with the teenagers and they seem more down to earth and don't force conversation.
It's really annoying me now though because I just don't have motivation to talk to people and I look like a grumpy/shy loser with no friends who sits by himself all the time.
Everyone is forming groups already, there's one or two girls that seem "warming" but I just don't think I'd have the motivation to sit around people for a whole 45 minutes at lunch. I usually go to the pub by myself and eat something an have a pint.
Is anyone else like this? Am I weird? I'm 20, I hate typical college kids and teenagers, I'm fine at work but when I want to study I work by myself, I go in, learn, go home. I don't want to listen to how someone got laid on the weekend.

Help!
