Granted but you travel back in time and accidentely kill your past self in a attempt to eat the pizza again to fuel your new found addiction to that pizza which causes a time paradox and you cease to exist.
I wish for for the wish of the person below me to not get corrupted.
Granted, whenever you get tired, you just suddenly fall asleep and go thump into the ground cause your brushing your teeth before bed or showering before bed or reading a book before bed or other before bed time stuff.
I wish that the the person above me was always tired.
