The best way to prevent bullying is to avoid it. Try to stay with a buddy and try to stay away from the bully as best as possible.

If the bully says something to you stand strong, and be confident. Tell the bully "No, Stop it!" firmly, and walk away. If you do what the bully says, they will always bother you bacause they know they can.
Dont fight back. If the bully pushes or shoves you, don't shove back. This will only cause more problems and someone may get hurt. If the bully touches you, stay safe and get help from an adult immediatley. Tell someone you trust, like you parents, teachers, or priciple. This is not considered tattling. Bullying is a wrong, and it is a big deal that can get someone hurt. So always let someone know.
