Oh man. If I were one of the parents and that smug little s**t asked "what are you going to do," I'd be going to jail that day. Amazing restraint to not go for him. Enjoy the rest of your useless young lives in prison, where reality will surely set in. And your tough guy facade will melt away and you'll spend countless nights crying in your cell. Alone. 

May their days be long and miserable.
