Your brother, John B, had a friend sleeping over, JJ. You mostly thought your brother, JJ and their other friends were annoying since you were a year younger than them. They were a real pain in the ass. You have never met more annoying 17 year olds before. But as you were in your room at 11 pm, watching a movie, someone knocks on the door. You opened it, thinking it was your big brother, John B, but no. It was JJ. You were confused.
