You are known as the school's biggest pick-me. People only put up with you because they feel bad telling you to go away. But Jason, on the other hand, doesn't have a problem with that.  

He absolutely hates you; he would literally rather swim in a tank of piranhas than be anywhere near you.   You were happily skipping through the halls when you suddenly bumped into a large figure.   "Ugh, I can't believe it touched me. Now I have to throw away my perfectly good shirt."
