I'm not a big joiner, and generally anything requiring a group effort to complete will send me running for the exit. (Except for my own field, construction, where everything is cooperation and coordination and collaboration, which I enjoy.)
But I do like the relaxed atmosphere of the open classes at my LQS, where we all work away, share what we are doing, and get help if needed from the instructor. We chat or work. I talk to myself a lot. People are who they are and we all make an effort to be nice to everyone else.
