"No, Carlie, I'm not," Paul said, his sternness still apparent.  "When you say the words, but spit them out like an insult, you take away all meaning."  He glanced to Celeste, and then back to Carlie.  "Look at what you've done to your sister!  Celeste has never tried to hurt you, Carlie, and you've done this to her.  I understand that you're upset, but you have to realise that violence isn't an acceptable way to express your anger."
