By looking past their tough exterior into their internal motivation and struggles, you will probably find an unhappy, fearful person. You could be bullying you because they are copying the behavior of the person who is bullying them.
The Bullied:
What should they do?
Stand up to the bully. Be assertive, but not aggressive.
Try to stay calm and walk away quickly.
For me, I ran, and he caught me.
Firmly tell the bully to stop and look them in the eye. After the bully clocked me in the face, I turned toward him and looked him in the eye. He got impatient, and his friends told him to come along; they wanted to get going.
Immediately tell a trusted adult.
Seek good friendships and stay close to friends when you are in an environment of possible bullying.
