The Simplist Way

After pulling the wishing stone from her bag, Sabrina said "I wish that Jon and Karyn would forget that the wishing stone exists." The stone glowed in her hand, warming it a bit. Down the hall a little, Karyn and Jon looked confused. "What were we just talking about?" Karyn asked. "I don't know. I think I was looking for something." "What?" "I don't know. I can't remember," Jon said, pausing a bit to think about what he was looking for. When he couldn't think of it, he said "You know what, it's probably not important." Jon and Karyn walked down the hall, talking about something else. Sabrina turned around and smiled, thinking that she had erased all evidence of the stone. She could now continue to have her fun, uninterrupted.
