I am currently experimenting with being social for its own sake. I am pretty good friends with the people I work with, friends enough to have become friends with them all on Facebook. It's unmarked territory for me, but we do care about each other and I've been invited to outings and such (turned down, both times), so I'm just going to face the fear.
I want to have a network. I tend to avoid socialising because I'm afraid, and I just won't let it run my life anymore.
