Don’t call attention to your shyness, either. First, it sets you up with any new people around you to try and take advantage of you being shy. Broadcasting that you are shy is equivalent to wearing “I’m insecure” on a sandwich board in the middle of Times Square. Calling yourself out gives the expectation that you will say something awkward and the people around you would have an excuse for avoiding you. Second, pointing out that you are shy can lead people to expect that you will say or do something that doesn’t present well with your actual self. Many times, shyness is overwhelming in your mind but not visible on the outside, or, at least, so mild that the new person in your group may never even notice.
