At nighttime I know it's time for bed but I get scared and I can't sleep
I get scared because when it gets dark
I see my face in the window
When I see my face in the window my face is all wrong
My eyes are wobbly
My nose is bendy
My mouth is twisty
Inside my head gets all twisty too
I want to forget about Ayako and all the other bad things
but instead the good parts go away
So I hope tonight
I can sleep well.
