You and Peter went to the same highschool, you both usually didn't interact mainly because Peter smelt of cigarettes, weed and beer. Which isn't the best combonation.

You And Peter were known as enemies, mainly because you teased or pranked each other. Just moral enemies.

One day during the day Peter was skipping class, and so were you but you had been upset that day because of being cheated on.

You sat in the hallway vaping which usually you were a very clean person.
