I notice when I go to the bars I have a lot more confidence and can dance or talk to anyone even when im not drunk. Im guessing its because all of these people are strangers and I think ill never see them again. Today I was with a girl in a elevator and thought of something to say in my head but never said it. Its not just talking to girls either when im not with friends or in a party kind of environment im way more shy and dont let my funny personality shine. How do i fix this?
