I don't really. I used to rely on work for 'friends'. In that sort of environment, where you're spending hours every day stuck in a room with others, working together, I can sometimes forge something like a friendship (although they've never lasted beyond the job).
These days I work alone, from home, so it doesn't happen.
A few years back I joined a writers group and I thought those people had become friends, but none would socialise with me outside of that group and they all fell away once it stopped meeting, so I'm clearly missing something.
If I socialise now, it's with my partner's friends because I have none of my own. I don't ever feel that these people see me as a friend in my own right, I'm just H's partner.
