Recognizes Sarah

Ali slowly put the pieces together. This was Sarah, she'd know through school! Sarah was the butt of all the popular girl's jokes and pranks, Ali included. The whole thing had culminated in Ali stealing Sarah's clothes in the locker room and making her run through school in her underwear!

"S... Sarah?" Ali asked fearfully.

"That's right, it's me." Sarah said. "Though, you probably remember better as butterball. Isn't that what all you pretty girls called me?"

"Well... uh..." Ali stammered.

That was in fact exactly what they called Sarah, plus many other, meaner things. And now, the girl she had so mercilessly bullied was babysitting her... while she was butt naked!
