T.J.'s movements were faster than her brain could function. One minute she was standing next to him throwing icecream on the counter yelling at him about his stupid stubborn attitude, and the next he was flat on his back and she had knees planted on either side of his waist and was pounding on his chest with her tiny ineffectual fists. Not hard enough to hurt him, not really, but at least enough that it made her feel better. He might have apologized, at least as much as boys knew how to apologize, But T.J. was still upset. 

"You fucking arrogant little… bitch!" She screamed, several house-elves scrambling back away from them as she raged. T.J. was not someone you messed with when she was angry. Even the house elves knew it. "I am not stubborn! You're just a jerk. You and.. You and Stupid." She punched him between each word, "Lizzie. Fucking. Grimm. Deserve. Each. Other." Then she pulled herself off the boy, standing, and pushing her hair back out of her face. "Fuck you. Fucking Fuck you. All I did was offer to help you." She snapped. She was furious and she couldn't calm herself down no matter how she tried. "I thought we were friends!" She shouted and stormed out of the kitchen, not even caring if he followed her.
