you are in the 9th grade and it's physical education class, you have a combined lesson with the 11th grade, you can't study for health reasons, and you are sitting on a bench near the locker rooms

but then some guy from the 11th grade with a split lip flies out of the locker room at your feet, who seems to have gotten into a fight with someone

"Oh, hah, sorry, I got into a little fight with my classmates"
