Zoe opened the front door. Karyn was there... no doubt she wanted to walk to school with Jon.
"Come in," said Zoe. "Jon's taking a shower. I think."
"Who?" replied Karyn. "Jon? You mean Joan?"
"Uhh..." said Zoe. "I mean Jon, my brother. You know, it isn't as if you haven't known each other since forever."
"Please, Zoe. There haven't been any guys in this town since like forever."
"What are you talking about? You're making no sense. You..." And then she noticed a picture of her parents on the wall. It was all wrong. Somehow her dad had turned into a woman!"
"You're telling me every single person in this town is female?" said Zoe.
"Well, of course."
"I don't believe it," thought Zoe. Her wish came true. If everyone in the town was female, everyone was like her, in at least one way.
At about that point, Jon came out of the shower and yelled "You can use it now!" But his voice had become higher-pitched. Zoe ran upstairs to see what had happened to Jon. Instead of Jon, there was a girl who looked just about identical... softer face, breasts, no facial hair... but still basically Jon.
"Karyn's waiting for you," said Zoe, and went off to her room. Just what had happened?
