Huh?

I am perplexed. I don't understand. Guys (yes it always comes back to them) like me. At least that is the word on the street. They think I am fun, and interesting. I throught a great party (or meet). I talk to much during movies but, hey at least I am entertaining. I truely like being around people and I think they truely like being around me (most of the time). Yet none of these guys that rave about how awesome I am (ok rave is a strong term) would never dream of dating me. Why?
A guy at dinner last night announced that he was trying to convince some people that most friendships begin based on looks. Not only boy girl relationships but same sex relationships also. We see someone who looks cool or interesting and we go over and make conversation. I believe that this is more true for guys then girls, but granted maybe he is right.
So lets bring this back to me (miss obsessive of how the world views her). They can stand to look at me enough to make conversation. To be dazzeled by my wit. But yet for whatever reason (be it weight or something else) they can't date me. The thought is so far removed from their minds that it might not even exsist. At least this is how it appears to me.
