I definitely think it’s a profession by profession case. As a teacher, our profession tends to bond outside of work because of the stress we are under. By going out for drinks, sports games, or lunch at a colleagues house, it’s a way for us to support one another even if we aren’t talking about the job (which is preferred). I used to shy away from such gatherings because fo my own schedule and that I perceived myself as too busy to attend, but discovered that the comaraderie my colleagues exhibited at work, was built outside of work. I know try to attend as many functions as I am able, even if it is just for an hour or so. Granted, this is a peer group, but I think letting your colleagues in your life shows that we are all human and have lives outside of work. Especially true when you go through hard times, as you have noted.
