Jon closed his eyes and jerked his face away from the blinding flash of light. He then opened them and turned back to the stone that he held in his hand, a feeling of dread settled in his stomach. Jon sat there on his bed, waiting for the wish to make something interesting happen; and he waited, and waited, and waited...
After waiting for what felt like an hour - though it was only ten minutes - Jon finally released his breath, he hadn't even noticed he was holding it, and wiped his brow.
"Huh?" said Jon quizzically, along with a bit of relief in his voice, "I guess I will have to wait until tomorrow morning to see if something has changed. I hope it isn't anything too out of the ordinary." With that he went to sleep.
What Jon didn't realize, was that the wish was already in effect and that it was already changing his reality into something else.
