I'm not a really loud guy. Only around my really good friends. But when a group of [simple] friends get together somewhere, I don't say much at all. Because I never really have anything to add to the conversation, and I'm afraid of making myself look stupid or obnoxious. One time, a friend even called me out on it: "Glenn, I forgot you were even here, you haven't said anything." I guess it isn't awkward for me because I'm used to doing it so much. It's only awkward when I'm kinda outside the group (i.e. out of the physical circle of people talking).
