Oh and I should say that the best cure to the last has been, of course, experience. I'm realizing that I'm unlikely to be shot or knived, or even punched, by someone I'm not getting (I think I was maybe too sheltered as a kid or something, that I had this overblown fear of anyone very different from my prior experiences), and at worst maybe they'll make fun of me behind my back to their buddy for my way of doing things. Or maybe they're as worried about acting stupid in my eyes for all I know. I just try to relax a little more and worry a little less.
