"I wish my previous wish would reverse itself, like it never happened," Mikey said.
Sarah took the stone back. "I wish that one of the people who is living a different life because of Mikey's wish would reenact the terms of his wish starting tomorrow morning, exactly the way the people affected did, only changing with people also changed until everyone is back to their original selves, and that I am the last person to change, and that I'll be aware of what is happening when I do."
The stone glowed for a moment, finding it acceptable. Sarah looked at him. "Just to be safe..." she said. "I wish that this stone, when the other wishes I just made are complete, would appear in the hands of someone who with it would do the most good."
