"I wish that, over the next week, each person living in this house will swap memories and personality traits with one other person who doest live in this house, and by the seventh day we will completely believe that we are and have always been the person we swapped with, despite our outward appearances. I also wish that whatever clothes we decide to wear will change to fit our bodies. I wish that, one week after that, we will return to normal and I will be the only one to remember the changes."
Jon sat back, wondering when the changes would begin. Now all he could do was wait. But a thought occurred to him: would he notice when his memories began to change, or would the new memories seem just as real as the old ones?
