Surprisingly, I put a massive amount of effort into cooling my jets when it comes to my quirky behavior. I don't act as giddy or over-the-top as I do when I'm with people I know, and I try to cut back on how much I say about games, films, anime, cartoons, comics, etc.
sadly, this leaves me with very little left to talk about, and thus I can't hold a conversation with someone about it. Which is kinda annoying for me, because there are a lot of people I would love to get to know, but I know I can't because I can't hold a conversation with them. 'sigh'
Also! the guy who started this thread: I talk to myself too. I clam up when I see someone else nearby, too. ANYONE. Although I tend to act out fantasies in my head, and i fell both embarrassed and defensive about them when someone see's me talking to myself.
