Making Others Forget

After school that day, Jon sat in his room, wondering what he should wish for. "First" he thought to himself "I don't trust Karyn with the stone, she could cause harm to me. So I'll deal with that first." He wondered how he should word his wish. "I guess it wouldn't hurt to make me the only person who *knew* about it." he pondered. "I wish that me, Jon Gibson, would be the only person that knew about the stone, and it's powers" The stone emitted a light flash to confirm his wish.
