Theres this guy, who would just take my stuff and write on it. For example, he'll take my sketchbook, and just start drawing in it. or one time he took my keys and started writing his name on it. One think that pisses me of the most, is he copies everything I say. Or he'll take my keys and walk off with them, and ill be like "give me my keys!" and he'll mock me in a higher pitch -_-. what's his problem and why does he act like a freaking jerk?
