These two girls weren't her friends. They were both someone else. But from their faces, Sarah thought they kind of looked like Biff Meadows (her boyfriend) and Steve Farber. The girl she thought was Tiffany had Biff's face and the one she thought was Melissa had Steve's face. They could have been their sisters.
"It's no problem, Sarah," said the girl who looked a lot like Tiffany, but had a female version of Biff's face. Sarah noticed that the girl's voice sounded a lot like Biff's, only higher-pitched.
Could it be that her boyfriend had turned into a girl? This girl? It seemed almost too unbelievable to imagine. People didn't just change genders overnight.
"Hey, here comes your boyfriend," said the girl who looked a lot like Melissa, but had a female version of Steve's face.
Sarah turned around and saw a muscular boy walking towards her. But it wasn't Biff. Oh, his body and clothes looked very similar, but his face belonged to someone else. In fact, his face belonged to Tiffany Sanders!
