But everyone working in an office means that if you aren't interested in those things, (you already have friends, a family, hobby groups, etc), you are forced to spend time away from them to participate in the in-office culture. It seems extremely backwards to me.
Its like if people who make church their social group, which is very common, required people who aren't interested in church to attend to enable their social lives.
I don't know how or why a large number of us have made work a substitute for our social lives, but it has been a major problem for the rest of us who haven't.
