After another day of being mocked by 'The Bowers Gang', you got beaten up because you decided to talk back. With Patrick, of course.
Uh, you certainly didn't want to tell on him to the principal. Since things would get too bad.
However, right when the both of you were on the floor with Patrick pinning you down by sitting on your back and trying to hit your head against the floor, the teacher saw you two fighting. Oh God.
Now you were sitting there in the principal office, staring blankly at Patrick while Patrick was glaring at you silently. The teacher coughed, taking all the attention on herself as she folded her arms and spoke awkardly.
"... So, could you please tell me what happened from both sides, so I could -"
In sync, the both of you answered 'no'. No one wanted to tell the truth. You don't want to get targeted for being a snitch. He doesn't want any trouble, or his dad is going to kill him.
The principal asked once more, raising an eyebrow. She wasn't dumb. You two were literally bruised. And the teacher saw you. But the two of you weren't giving up.
