Answer:
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 teeth are sharp, my back is straight, to cut things up it is my fate.
I walked and walked and at last I got it. I didn't want it. So I stopped and looked for it. When I found it, I threw it away.
Whiling away the hours of flowers, Walking through fields of gold. Preening and pruning in lights fading hours, For petals to freeze in the cold. What is it?
When there is fire in me then I am still cold. When I own your true love’s face then you will not see me. To all things I give no more than I am given. In time I may have all things, and yet I can keep nothing.
I go in hard come out soft. Blow me hard and I’ll make a pop.
