The Futility of Violence
When I was in school there was a big kid who thought it was fun to shake hands with other kids and then painfully crush the smaller kid's hand in his meaty grip. He tried this trick on me one day, so I merely smiled as he started to apply pressure then flipped his hand up putting him in a painful wrist lock and pushed him back. He sure learned a lesson that day. He never tried to crush another kid's hand while shaking hands after that. Instead he'd flip the other kid's hand up into a painful wrist lock. He found that much more satisfying.
