"Let's start having some harmless fun now. Would you rather lose half your height or half your length?"
'What the heck does that mean?' Jon wondered. Losing half his height was fairly straight forward but what would losing half his length entail? He'd only been thinking about it for about a minute before he got another text. "Eating dinner. Be over afterward."
'That must be from Karyn.' Jon thought. He was about to set his phone down again when it buzzed alerting him to another text. "Choose quickly. In 2 minutes if you haven't you'll get both."
'Shit. I don't want to be under 3 feet tall.' Worried that he was making a terrible mistake and giving away half the length of his life or something Jon sent a reply to the mystery number: "LENGTH"
Almost immediately he got a reply "Good choice. I hope you enjoy it. We'll play again soon."
Jon began checking out his body for changes. His quick inspection didn't reveal anything obvious. Maybe it was all some sort of practical joke somebody was playing on him. Maybe he just forgot getting the can of Pepsi and nothing weird had actually happened.
After starting his homework and working on it for a while Jon realized that he had to pee and made his way across the hall to the bathroom. Unbuttoning his jean and reaching into his briefs Jon suddenly discovered what had changed.
Frightened at what he'd felt Jon dropped his pants and underwear to his knees and looked down at his crotch. Jon now knew what the mysterious texter had meant by "lose half your length."

He heard somebody coming up the stairs and then Karyn's voice calling for him from his bedroom.
"I'm in the bathroom I'll be out in a minute" he called through the door. After finishing up in the bathroom he went back to his room to see Karyn sitting on his bed looking at the stone and fingering it.
"Maybe you should put that down for a minute. We might have a new problem on our hands." Jon said.
Karyn set the stone back down on Jon's dresser and asked "So what was the big emergency that couldn't wait?"
"Well it all started..." Jon began until Karyn held a hand up when her phone chimed in her pocket.
"Just a second. I just got a text." Karyn said pulling out her phone. "What the heck does this mean?" Karyn asked turning the phone so that Jon could read the screen. "Would you rather..."
