Everyone started treating me different why do peple do this?

Screw other people and love yourself for who you are. High school is a lame place where everyone judges everyone. If you are true to you the rest will follow. And like someone said pretty people do get treated differently. I think you should ask this guy who likes you for help on homework or soemthing. Even if you don't need help ask him. It will make it so you 2 are alone together and men love to feel needed.
