I understand that you don't have a lot of control over this, and it's not at all easy for you. I think you get kudos for getting out there and attempting this.

To be honest, I think I would be a little put off if you gave me a dirty look or tried to hit me when I sat down. As far as moving over, or pulling into yourself, I tend to do the same. I don't want to make eye contact. I'm afraid someone might try to talk to me, which shouldn't really be a big deal, but somehow is. I tend to look for a spot where I won't be near anyone else. I would probably try to give you as much space as possible, just cause I'm more comfortable that way also.
