Answer:
I lose my head in the morning and regain it back at night. What am I?
I run up and down the stairs without moving
Brown I am and much admired; many horses have I tried; tire a horse and worry a man; tell me this riddle if you can.
My first is in some but not in all. My second is in tiny but not in tall. My third in little but no in big. My fourth in port but not in pig. My whole is made in nature's way. For clothing rugs used every day.
One pace to the north. Two paces to the east. Two paces to the south. Two paces to the west. One pace to the north.
No matter how little or how much you use me, you change me every month.
