These cliques may be formed by just a few people, but when they're accepted they become the rules for popularity. A fear to cross these social lines develops, fear of becoming an outcast yourself. It's appalling how far these social classes are taken. I'm amazed to see how a person will treat a peer as not as good a person as them self because of their social status. Remember that what people think of you in you small little spot on the planet isn't as important as it may seem.
People insult each other with such thoughtlessness.
My plea to fellow high school students is to have some empathy, remember how it feels to be insulted. Forget for a moment your reputation, the social classes in your school, and strike up a conversation with someone new. Who knows, you just might start a trend and build a stronger bond of community within your school.
