Why can't you be nice?

Really pissed right now. Its just paper, get over it. Its not a big deal, you don't need to be such a baby. I'm getting really sick and tired of you always saying those stupid but hurtful things to me. Like saying "look at you, you're so dumb" and "your face is so stupid haha ". Yeah that shit starts hurting after 9 years. And yeah I say stuff back but only because you think its funny, so I don't think it hurts you like it hurts me. You need to be careful what you say and how you say it. Because its really starting to build up.
