Attraction! - Male/Female Friendships

I have recently come up with a theory about the relationships between males and females. Not that I have much to base my theory on but a few observations. I know some girls who have a lot of guy friends. When I am at their house there are always different guys coming in and out to visit and hang out. All the girls are single and I began to wonder why, if they were such good friends with all these guys they don’t date any of them. This is when my theory began to form. I have decided that for girls and guys to be friends there has to be some reason that they don’t want to be in a more serious relationship. There has to be some form of attraction between them but for some reason it doesn’t work out. Either one person is attracted to the other but the other person does not return the attraction, or maybe there are circumstances that they both know it will not work out, or some other reason. But attraction is always involved. So then I tried to think of a way that guys and girls might be friends even if they are both unattracted to each other. I couldn’t really think of a scenario that would fit without some sort of attraction. I then asked another girl and her response was “Maybe they like their personality.” That is attraction! So in conclusion (as well as I can conclude) I think that there must be a form of attraction between guys and girls to be friends but also some reason that would cause the friendship to not form a more serious relationship.
