Be a Buddy, not a Bully. Say there's someone who may not be as good looking or popular as others or they have to wear glasses or can't afford to have the cool things, maybe their life is hard enough and they find it hard just to try and fit in. To bully them makes the bully much weaker than they are because a bully doesn't understand how much strength it take for them just to make out through a normal day. Be a friend, be a pal, be a Buddy Not a Bully.
