Not everyone is going to like you. You're gonna end up going through life disappointing a countless number of people. The reality is, what you give is what you get in return.
If you're an asshole to someone, chances are they're going to be one back to you. Maybe even worse. Nothing is more irritating then people who can be just so nasty, so cruel to everyone- then expect everyone they've bullied to be nice to them. You can't treat someone like crap then expect them to love you. That's what people have yet to figure out in this school.
