Question

I did not start the fight with Marcus. I was walking down the hall when Marcus came up and pushed me for no reason. He said that his buddies told him that I had been making fun of him. But I never said a thing! Marcus swung at me, but he missed. I tackled him, and that is when Mr. Rhodes broke it up. It wasn't my fault. Marcus started everything!
