Kevin reached for the hat as it levitated off of his head and towards the Professor but he missed by an inch and he nearly tripped over the table. This was it, his "secret" was revealed. He quickly covered the top of his grey hair with his hands and GLARED at the man. "I DON'T GET YOU PEOPLE!" He SHOUTED throughout the class and even slammed his fist on the table. "You ALL tell me that i should be NICE and i was and its STILL not good?!" That was it, he knew that being calm and nice was just for losers. He had been right all along. Grown ups were mean and did not care about anything but themselves. "From now on i'm NEVER being nice again, ever!" and then he leaned back in his chair, crossed his arms over each other because everyone probably already saw his greying hair and placed both of his legs on top of his desk. Narrowing his missmatched colored eyes at the Professor as he kept staring at him with a glare.
