Let's be realistic here. I mean TRULY realistic. Like it or not, certain women are out of certain guy's leagues, and vice versa. Most of the time, you see attractive women with attractive guys. You seldom see a hot woman with a fat ugly slob. You don't often hear about rich people dating poor people. Doctors typically don't date maids. Celebrities don't date nobodies. You get the idea. This whole process usually takes on a real shape around junior high, but there's even shades of that in elementary school. How do you think cliques are formed, and what do you think they're based on? I used to think that this type of thing disappeared after high school, but it doesn't; it continues in adult life, only without labels such as "jocks," "cheerleaders," "nerds," "burnouts," etc..
We are each in a league of some kind, whether it's based on looks, money, social status, education level, profession, etc.. By that same token, women who look like Catherine Zeta-Jones don't date guys who look and dress like Michael Moore. If Michael Douglas wasn't an A-list Hollywood legend who's the son of an A-list Hollywood legend, do you really think he'd be married to Catherine Zeta-Jones? C'mon now.
When you view the profile of a total HB9 on Myspace, and you see pictures of her and her HB9 friends at a club lushing it up, you can that if there are males to be included in there somewhere, they'll usually be buff, handsome guys. When you do see something like that, you instantly recognize congruence there. In the rare event that you find a pic of a HB9 with some Michael Moore-looking slob, you're inclined to wonder "What's she doing with him?"...that is, of course, if you haven't already deduced that they're just friends. Birds of a feather really do flock together.
