Did you ever have to fight a bully growing up?

A bully kept harassing me when I was in school. Every day he would walk up behind me and hit me in the back of my head with a book. One day I had enough. I followed him down the hall, knocked him to the floor from behind and slammed his face into the ground repeatedly. The Teachers had to pull me off. His face was bloodied and I broke his nose.

He never bothered me again.
