i wish one week a year you could spend each of the seven days in someone else's existence. not only in their body, but living their life, with all of their thoughts and feelings.
no, sush, you can't be avril, or any other really young famous chick, so you could look at yourself in a mirror a creepy way all day.
(j/k, i'd have to say eva would keep me home all day)
it would be a random selection. you'd wake up as that person, and actually be them for a day. then, at the end of each day as you went to sleep, you'd be yourself again, and remember all of your experiences.
i think it would teach the world a little compassion for each other, instead of so much greed and aggression.
