I do worry about that, too, Fuzzy. Even in school I was always having trouble expressing myself. I found in later years that I was considered "stuck up". I never though of myself that way and feel that it stemmed from my trying to curb what I wanted to say because I was afraid of expressing myself. I do a lot of re-writing when I post on PC because I'm worried that my words will hurt someone else or make them feel bad. Sometimes I will even delete a post if I can't convince myself that it is helpful and supportive. So you are not alone.
