I consider myself shy, but other people dont?
I was always shy growing up. Elementary school, middle school, and the first few years of high school was when it was the worst. At my junior/senior year I started to break out of my shell. Right now I'm in university and I still consider myself shy, because I have my whole life.
But my RA says that I am one of the least shy people he knows. I participate the most in every one of my classes. I always talk really loud, am really blunt, and have no problem confronting someone who is being an asshole. I don't think that has to do with being shy though. If I'm at a party or something a lot of the time I'm too nervous to go and meet new people. But I have no problem doing that stuff in the beginning of a semester. I heard somewhere that if you think you are something (ex: introvert, extrovert, attractive, etc) than you probably are.
