J can sit in a chair and fall sound asleep. I can't do that because, for me, falling asleep requires a horizontal personal orientation. That is the true definition of a nap. Ask the cats. Neither of them will fall asleep sitting upright.
Miu has been asleep on top of the cats' condo and had her head slowly slide until it is hanging straight down off the edge. I can't do that either.
I require a bed and a pillow. I am so untalented . . .
