Cousin did a group project which one girl presented and took all the credit for. The rest of the group got 0 and the teacher won't listen to any explanations. Cousin understandably has violent feelings towards said girl.
Said it'd be more effective to get that teacher's inability to listen in writing, then escalate it. But apparently beating an apology out of the girl is the more appealing option because it's not "boring".
I give up.
