How are you going to stop kids from making fun and being mean to each other? Please tell me. You can't legislate this. It's part of growing up.
Adults arent even nice to each other and they expect kids to be? Yea right. Tell your kids to put on his big boy pants, its part of life.
Eh... it's nothing a few beatings can't fix. Sometimes, the only way you can get someone to sympathize with the suffering of others is to make them suffer themselves.
