Sarah was still bewildered, not quite understanding what was going on, but went with Biff anyway.
As they walked, Biff began to speak faster and faster. Sarah grew more and more bored. Why wouldn't Biff stop talking? Why couldn't Biff at least talk about something interesting?
She wondered if she could find someplace quiet in the mall where they could make out. That would put Biff's mouth to better use.
Sarah suddenly blinked again, confused, unsure of where these thoughts were coming from. Biff wasn't a girl, he was... Sarah turned back to Biff and nearly flipped out. Where did that cleavage come from?
Sarah was so distracted by that realization, she walked right into someone. "Why aren't you watching where you are going?" They said, angrily.
