Proving The Truth

"No. It's mine!" Jon yelled back. "You don't even know what it is. So just give it back, okay?" "I know what it is. It's a wishing stone. And it's *my* wishing stone." "How ... how could you know that?" asked Zoe, confused. "Because Grandpa gave it to *me*." Jon got up and sat on Zoe's bed. "Now to fix this mess." "Fix *what* mess?" asked Karyn, who just walked into the room. "I switched my personality with Zoe's. I'm having some weird thoughts about all of this. I don't think I want to ..." "You have *my* personality?" Zoe said, obviously not believing him. "There's no way I could be like *you*." Then, just to prove to Zoe that he was telling the truth, he said "I wish you would know the last wish made with the stone." The stone glowed and Zoe's eyes went wide. "What is it, Zoe?" asked Karyn, concerned. "He's telling the truth. He *did* wish that." Jon got up and brushed past Karyn. "Hey! Where are you going?" Karyn asked. But Jon didn't answer. He just went back to his room. A few seconds later, they heard his typical metal music blaring for all to hear.
