Why is it that whenever I am around a chick that I have absolutly no interest in I feel like I have to watch what I say or do so I do not accidentlly trigger her interest and generate attractioin in her, but when I am around girls that I am interested in, I seem to freeze up and seemingly "forget" how to do things that I know work and that I activily avoid in other situations. This just makes no sense to me at all and it frustrates the hell out of me.
