Isnt it strange?

Human attraction is such a strange thing. That is, the attraction between two people with romantic ideas. I just dont get it? But does anybody? I have this new theory that I can tell within 5 minutes of seeing and talking someone whether or not they are someone I could be attracted to. Now I accept at this point it is flawed, because my own history shows that I have been wrong about this. But I still think that it works most of the time. Most recently an example would be this: Theres this girl I had a few classes with last year, I always thought she was very pretty, seemed incredibly cool, just my type of girl. I also never talked her. Recently I found her on myspace (lame, I know) and we started talking. We ended up hanging out about a week ago. It was a fun night, and I was totally right about her, I think she could totally be my type of girl. And other than me totally being strange at the end of the night and I think accidently giving her the impression I wasnt at all interested, I think she had a good time too. Well I did my best to make sure I made it clear to her that I actually was interested. I think. But now Im getting off track. The point is, I had never even spoken to this girl (well, we may have said "hi" once or twice, but thats about it), but I still knew that she was someone I could get to be very interested in (Actually I still dont know for sure, but I have a feeling, I need to spend more time around her). Ive also known instantly that girls that are clearly quite attractive just arent my type, so I know its not even worth bothering. Maybe this theory just comes from all the experience I have had with girls, so I just know quicker. Or maybe it comes through cynicism, after having my heart broken a few times I dont even want to bother trying unless a girl fits a certain mold. Then again this latest girl doesnt really fit any mold, which is good.
Beyond that, its so strange that one person could be totally into another, and the feeling be not at all mutual. At the time, I can think of at least two girls who are interested in me that I have no interest in at all (Im not trying to brag, I bet if anyone thought about it, they could think of one or two of these people, too). They are both attractive, have nice personalities... they just do absolutely nothing for me. And I have been on the other end of this as well. Ive been extremely interested in girls who dont want to even bother with me. I guess sometimes we just have to accept that "its just not there." And thats the thing, we cant really define "it." "It" is intangible, really undescribable other than saying its that certain something that makes us attracted to someone. Although we can not confuse "it" with liking someone just because they dont like you. I am the king of that, wanting someone a lot mroe simply because they dont want me. Its like a challenge. But we all know that Im an idiot.
Human attraction is a funny, sometimes its exciting, sometimes overwhelming, consuming, intense. Sometimes it drives us crazy, breaks our heart, and makes us cry. But I guess its all just a part of the human experience. And really its all pretty funny when you think about it.
