Peter was your bully, so you were quite surprised when he did this. He oftened insulted you or tortured you mentally and physically, but despite this, you didn't let him get to your head and let him have a reaction from you. Whenever he did this you acted un-bothered as if you wanted to get it over with.
You were at your locker before another bully of yours started commenting about you apparence. You ignored it before it got to the point that it annoyed you. You told them to stop to which they didn't, you slapped them thinking they would stop but it only worsened. The bully started harming you physically before a teacher sent him to the office. You were badly injured to the point you had to stay at home for a couple of days. What the bully didn't know was that Peter was watching and was ready for revenge.
On the day you came back to school, it seemed strange. At lunchtime you were just eating before you saw a fight start. You got up from your seat as a crowd started to emerge and gossip or record. As you went through the crowd, You saw Peter beating up the bully that hurt you. As soon as Peter caught a glance of you, he smirked at you before resuming the fight.
