As Jon was lying on her bed, trying to think of a funny but not hurtful joke to play on Karyn, she heard a knock on her door.
"Jon?" giggled the voice on the other side, "can I come in?"
It was her little sister, Zoe. She was two years younger, and entering into a bit of a goth phase, dying her hair black and getting a lip ring. She didn't wait for Jon to respond - she just barged in, laughing.
"What's so funny?" scowled Jon.
"You're stupid. You're really, really stupid." laughed Zoe, "you really shouldn't have that wishing stone if you're gonna get duped every time you use it."
"What are you babbling about?" Jon sneered. Her sister was always a bit of a pain, but now she was being especially annoying.
"While you were out, you left that rock in your room. Well, you know how I sometimes skip school and snoop around your room?"
"I do now," grumbled Jon, sitting up on her bed to listen.
"Well, I found the stone, and the letter from grandpa. And I was a little mad he didn't give it to me, so I used it."
"What did you wish for?" Jon was getting angry, her face was reddening.
"I didn't know what to wish for, so I wished I'd always know when a wish was being made, so that I'd never get tricked into thinking something was supposed to be how it wasn't. And boy I'm glad I did."
"Get to the point!"
"Well I was at the park with some friends, just chillin', when I realized that Karyn had made that wish for 5 minutes that your hair would be like hers. All of a sudden it just hit me. Then it hit me again--" she started laughing uncontrollably, but managed to say, between gasps of laughter, "she wished - that for one day - HAHAHA! - she wished, that for one day, all your clothes, hahaha... were girl's clothes! And then you-- you stupid idiot! Hahahahahaha! You thought she wished you were a boy! So you wished you were a girl! HAHAHAHAHAHA!"
"You're insane, Zoe," Jon laid back down, not believing her at all.
"Oh really?" her laughter died down, "Explain to me then, how, if wishes can't be undone, how you could wish yourself into being a girl?" Zoe snickered. "But this is great! Now I've got a sister. We can share clothes, gossip... it's going to be so much fun."
"It's never been fun," muttered Jon, "you've always been a pain, and I'd never borrow your clothes."
"That's only because you don't remember. You don't remember anything! Think about it, does any of this make sense? Really? Your mind is trying to cope with, like, two different realities, and the one that makes most sense is you being a girl... but you're just insane!" Zoe turned back toward the door, and was about to leave, when she added. "Hey, if you don't believe me, just wait until tomorrow when all your frilly pink outfits becomes jeans and tee shirts and boxers... maybe then you'll want to borrow my clothes."
"You're a huge bitch, you know that?"
"Maybe so, but at least I'm smart enough not to be tricked into wishing myself out of my own gender." She walked back out, then poked her head back in and said, "If you ever want my help, I might be able to think of a way to get you back your manhood."
Jon threw a pillow at Zoe's face, but she was never that athletic, so it missed. Zoe left, and then Jon buried her head in the covers, whimpering "I never was a boy..."
