I hate to say it but… you hit the bully back. I was bullied in school, and that was the only thing that made a bully stop. Of course, don’t pound them into the ground, and do it when the teachers aren’t looking.
That was advice I got from a teacher, and it changed my life. Before, I’d gone to a teacher when I was bullied. I tried to ignore the bully (he hit me in the head with a rock for ignoring him). I tried asking the bully to stop.
Then one day my science teacher said, ‘sometimes, you have to hit back’.
