I had stood up for one of my friends that were being tormented by some guy that thought he was tough, and funny for making fun out of someone. The bully was making fun of my friend for his interest in Japanese culture, (anime).
Now, you have to understand my group of friends are sort of the nerdy/geeky bunch that love learning, and video games. I couldn't let this bullying pass, because it would only fuel his ego. If he wasn't stopped earlier, it could've been a more intense situation, if my friend had snapped on him or any physical bullying were to happen.
I felt pretty bold insulting him with logic, even though his head seemed to be as hard as a cement wall. I continued and threatened to call the teacher. He may have called me a tattle tale, except it doesn't bother me knowing that I had protected my friend.
I didn't need a teacher's help, but I mean it does scare some people sometimes, especially if you're serious about it.
