I am 37 years old and have heard the very same things my entire life. "Too quiet" Is something I have heard a lot of as well. Once again, my is very situational as well. Yes, it is frustrating to be judged! I have been told that I come across as "rude, or stuck-up" I am glad to hear that I am not alone. In dealing with these type of people, I have found over the years, that one snotty, well-timed, snide remark will often make someone back down. I agree with Cheeky the "I don't care attitude" has worked the best
