Saints & Roughnecks

In our school, there are both saints and roughnecks. Even in my friends group there are some that never get in trouble and some that always get blamed for everything. With our school having a lot of middle class to upper class kids, there are probably more saints than roughnecks. Most people would not expect the well dressed, preppy, smart kids to be trouble makers in school nor out of school. But the truth is that they are the ones that are doing the most partying. The big houses, the money, the parents that don't give a shit about what their kids do usually are the rich ones. Then we have the roughnecks in our school. The minority's are stereotyped as doing drugs and partying all the time. They don't have the big houses where they can party at or the money to do w.e they want. So instead, they drive around not doing much most of the time and maybe once in awhile someone could have people over. I find that my friends with less money have stricter parents than the rich parents. Going back to my friends group, I have one friend that says every time he goes to the bathroom in school, a security guard follows him in. He has the skater look instead of the preppy look like most kids. So just because he wears a hat and some skater clothes makes him a trouble maker?
