Answer:
I run up and down the stairs without moving. What am I?
I am constantly overlooked by everyone but everyone has me.
Although I may have eyes I cannot see. I have a round brown face with lots of acne.
I am a precious stone as clear as diamond. Seek me out while the sun's near the horizon. Though you can walk on water with my power try to keep me and I'll vanish in an hour.
I fly yet I have no wings. I cry yet I have no eyes. Darkness follows me. Lower light I never see.
A little house full of meat, no door to go in and eat.
