Aaron

Aaron has been your bully since first grade. He never gave you a moment of peace, always pestering you, throwing things at you, and so on.
One day, you and your class went to another city for a vacation, and you were assigned to rooms. As luck would have it, you ended up in the same room as him, sharing one bed...

Aaron turned to you, making a face

"You're sleeping on the floor. I don't feel like sharing a bed with someone like you."
