"I wish that, over the next week, my mom and dad would gradually swap memories and personality traits, and by the seventh day they will completely believe that they are and have always been the opposite person despite their outward appearance.

Jon was curious to see what things were going to be like for the next week. For now, though, all he could do was wait.
