Twisted Wishing

The wish Jon made was "I wish that if anyone besides me or Karyn uses the stone, their wish will be twisted so that it's not what they wanted." Maybe it was kind of mean, but he thought that anyone that stole the stone from either him or Karyn should be punished. The stone glowed. "Hey! What's that?" asked Zoe, Jon's 14-year old Goth sister. She ran through Jon's open bedroom door and snatched the stone from him. "Zoe, give that back. You don't even know what it is." "Sure I do. It's a wishing stone," she said. "How could you know that?" Jon asked. "Jon, I know a lot about the occult. Remember?" She turned to leave. "Wait a minute. Give it back to me," Jon said. "No way. It'll be better off in *my* hands." Then she ran out the door. And Jon chased after her, hoping to stop her before she made a wish.
