It was a post-it. What was it doing here? Jason had no idea, but he felt curious, almost like he had to read it. He walked over to the neighbors' fence, on which the note was stuck, and pulled it off. It looked to have been there for quite a while; the ink on it was smudged from rain and faded from sun, but somehow he was still able to read it, muttering to himself as he did.
"I wish," the note read, "that I would have the genitals of the opposite sex."
Jason snorted and crumpled up the note, tossing it in the nearby garbage can. He went back inside, helped finish up the supper clean-up, and turned on the TV. After a while of watching different shows, he went up to his room and gamed until late that night; tomorrow was Saturday, after all, so he could sleep in.
After he'd checked his e-mail and shut his computer down, Jason began to undress. He pulled his shirt and pants off and stood in front of the mirror. Nuts. Still not much development to speak of. It was one of his great frustrations in life that he was one of the late bloomers in his class; he'd adopted the teenage mindset, he was ready to be one of the older kids, but he still looked pretty much like a sixth-grader.
Benny had had the same problem, until he got whatever weird disease it was that had made him decide to become a girl. Now Benny...er, Becky looked like any other thirteen-year-old girl. Jason got pretty weirded out whenever he thought about that; the idea that anybody would just up and decide to be the other gender was weird and creepy, even if they were sick like Becky claimed she had been. He shook the thought of it out of his head; it made him uncomfortable just to contemplate.
Jason opened his dresser and took out his pajamas and a clean pair of underwear. He pulled off his old pair and tossed them in the laundry basket, then stood back up and saw something that filled him with horror.
His privates were gone. Not ripped off or injured or anything, just gone, like they'd never existed. In their place was a slit; he'd never seen anything like it before, but it wasn't hard to figure out what it was. He had a girl's genitals, just like that note had said! Jason briefly began to wonder if Becky had been telling the truth, but the idea of magic sticky notes was just too ridiculous. He must be hallucinating; it was already one in the morning, he must be dreaming awake or something. If he went to sleep, he'd wake up to everything being perfectly normal. Nervous, but reassured by his deduction, he put on his underwear and pajamas and went to bed.
