Without it all the world is gray and dull for everyone. It reflects rays of sun, and yet it does not. It captures light, and yet it does not. What is it ?
In a morning bowl, it's me you drown. In a certain season coming down. I may silently fall from your crown. Which may evoke an observer's frown. What am I?
Never resting, never still. Moving silently from hill to hill. It does not walk, run or trot, All is cool where it is not. What is it?
