really weird that everyone has pillows. i don't think i know of a single person that actually has their head on it when they sleep. like, the top of the head touches it which is nice but you can't actually have your head ON the pillow.

i've even drawn a diagram so that you can look at it, see that it is also how you sleep and then agree with me
