I know a lot of people are hating on the security guard, but I actually feel kind of honored/special when strangers in that kind of setting feel that they can now have a real conversation with me because we've interacted enough that they trust me and consider me an equal. This includes the girl at the pizza store who now remembers me and says a friendly hi because I've been kind to her - not just at therapy offices. I think that when the receptionists at my therapist's office talk to me for real, even if it's in a vague way about another patient (it never is identifying), a) I feel reassured that they don't see me as a freak or an outcast or something undesirable, and b) I feel good about myself that I make other people feel comfortable.
