Don't tolerate bullying !
*Help the victim get away from the bully
*Talk to, listen to, and comfort the victim (it helps to let them know that someone cares)
*Talk to the bully.. tell them to stop (what really helps me when dealing with bullies is to say "Does it make you feel good to know that you're classified as a bully?)
*If taking action doesn't work, then try your best to avoid the bully (take different routes to/from school, find different ways to get to your classes, find another place for you and your friends to hang out)
If you are a bully... Just stop, bullying doesn't make you cool !
