There are a couple of these friends that I do make time to go out for beer with. So I haven't lost all of them. It's just that there is a group of people that I think are more than coworkers, but are still activity-based friendships where the activity is work. We're in the same department, we work in the same space, on projects which are adjacent but not necessarily joined. Take the office environment away, and the relationships fade. Yes that means they don't have the same value as a close friendship. But I still feel the loss.
