You never seen the film Birds? Chickens are worserer than that even. Think of rapacious pterodactyls, and that's chickens for you. Ever seen one sharpening a carving knife, whilst licking its lips and looking at you? That's chickens for you.
I often feel that when parents or administration want students to 'talk it out' and 'come to an agreement' or whatever... it's a way of avoiding accountability. Like they want to have their happy happy fun time dinner and call it handled? When really, getting stuff handled and taking accountability would be having a paper trail and being honest with the school administration.
