By the time Biff and Sarah arrived at school, they were fighting. It wasn't the first time. They had in fact broken up and gotten back together three times this year and it was only spring.
"Biff...I can't believe you are not supporting me in this!"
"Well, you're saying that everything you have done since we met was to make your mom happy and you want to wear plain clothes and kill your reputation and whatever...it sounds nuts."
"I'm trying to find myself," Sarah said. "And if you can't support me..."
"You go find yourself, babe...but I'm not promising I'm going to wait around for you to do it forever..." He threatened.
"Well, maybe we should just take a break for a bit," Sarah said. "If you were with me just because I was head cheerleader and you're the captain of the football team...then maybe you aren't the person I thought you were."
She stormed out of the car into the building.
Biff looked after her. That new guidance counselor had really done a number on Sarah. He decided to go and find out what she had said to make Sarah break up with him.
