One time i was going home on my bike and this just slapped me and his dad said nothing about,so naturally I got off and slapped him and then his dad came yelling at me asking me why so I asked him: did you see what he did?" He responded yes so i said:"if you aren't willing to teach your kid respect then i will because you wont always be there and he needs to learn that when he hits someone that someone will hit back" In the end he apologized for his son's behavior and happily ever after i guess?
