I seem to have trouble with casual interaction. For example, when I need to go get my haircut. I have to engage in conversation with the stylist when I'm AFRAID TO SAY ANYTHING. I have genuine difficulty with small talk with people. I never learned basic back and forth, small talk. I am paranoid, too so I think the people are being mean to me or misunderstanding me sometimes. I know that some other people have had this problem on this forum. Most people say they just don't go out and talk to people but what about when I HAVE to like when it's required?
