Anyway, these groups have always been around, and will more than likely be just as they are, in some way, for your whole life. From elementary to the workplace, there's always going to be different cliques. It's how people work, as herd animals. It kind of sucks though... But, it's not entirely rigid. I'm a bit of a loner in real life, but of the friends I do have, none of them are of any one set group.
