I had a fight with a bully and I am going to get them expelled.
Oh my, why did you two get into a fight?
I was tired of him ruining my reputation for no reason whatsoever.
Getting upset with someone for bullying you is natural. Be sure to tell your side of your story to anyone in charge. If you do, the bully could be properly punished and stopped from bullying others.
I have a plan. I'm going to tell the school a fake story and get the bully suspended and I'm getting out of this school.
No one likes a bully, but lying about your experience isn't a good idea as they will get their side of the story too and you might not get help with the situation you are in. How do you think the school would react if they find out your story was fake? I'd tell the truth.
