Abnruptly, Sarah said "What are you giggling at?" Then she immediately became confused. Just why did she say that, after all? "Tiffany, ignore that. I just...."
"What?" said Tiffany. "I thoought it was pretty amusing. I remember when... when..."
"Karyn got soaked with soda?"
"Now that you remind me, yeah, she did. It was red pop and it got on her hair too. What was her name again?"
"It didn't get on her hair because she had short hair, and her name is Karyn," replied Sarah. Then Sarah realized. Wishes change what is real, right? Wishing away Jon and Karyn would mean that nobody would remember them except the people who heard the wish. But the wish would take a week to finish, so it would also take a week for everyone else to forget them. That explained Tiffany, but why was Sarah remembering Karyn with short hair?
"Oh, Karyn. And her friend J... what was it?"
"Jon."
"Yeah, Sarah, J... him."
"I'm sure he'd want to be remembered," said Sarah.
"Why would you care whether some dork gets remembered? I mean, when Biff... when Biff...." Tiffany couldn't finish her sentence.
Sarah realized that any pranks that she and her friends pulled on Jon or Karyn were doomed to be lost to history over the course of a week, as if they had never happened. Only she would remember them. But wasn't it good that nobody would ever laugh again from having been mean to them? Sarah blinked. Glancing at Karyn's locker brought strange thoughts to her. She wondered if the contents of the locker would just vanish in an instant--lockers can't fade gradually like memories can. But why did it matter?
Once Tiffany was out of sight, Sarah returned to Karyn's locker and opened it. The remaining books were in it but when she looked closely she could see that the spare pencils were gone as well as that flyer from the mall. Sarah shut the locker and went off to class.
