While Jon and Karyn were at school, Jon's mother dropped by Wal-Mart to pick up some clothing for her new daughter. It'd looked, from what she saw, like Jon was about the same size and build as Karyn, so she'd called Karyn's mother and gotten some sizes to shoot for. She knew that it was only temporary, of course, but changes typically lasted anywhere from a week to a couple months in duration, and she wasn't going to have Jon running around braless in men's clothes for that long.
So she picked up some plain girl's clothing, mostly jeans and solid-color T-shirts with a few skirts and blouses, and of course some suitable (but not overly frilly) underwear. Jon's mother knew how to shop smart, and thanks to that and the fact that she didn't purchase any designer clothing, the total didn't come out to nearly what it might've. Gathering her purchases, she headed for home.
When she arrived home, she brought the clothing up to Jon's room and began to pack away the old male clothing in the dresser to make room for the new clothes. Grabbing a pile of dirty laundry off the top of the dresser, she found a rather unremarkable small rock. "Boys," she snorted. "Never throw things away, do they?"
She threw the laundry in Jon's laundry basket (which was conspicuously unused,) grabbed the stone, and took it outside and dumped it in the garbage can, just before the garbage collector arrived and emptied the can into his truck.
Meanwhile, during lunch, an involuntary shudder ran up Jon's spine. Karyn looked concerned. "What's wrong?" she asked.
"I don't know," Jon replied. "I just...I dunno, you could say I had some sort of bad premonition."
Karyn smirked. "Turning superstitious on me?" she laughed.
Jon smiled slightly. "Yeah," she said, "you're right. It was probably nothing."
