Never resting, never still. Moving silently from hill to hill. It does not walk, run or trot. All is cool where it is not.

Why this works

This riddle describes sunshine in a poetic way. The phrase "never resting, never still" captures how sunlight continuously travels across the sky as the Earth rotates. The line "moving silently from hill to hill" refers to how sunlight illuminates different areas as it moves, casting shadows and creating warmth, while "All is cool where it is not" indicates that areas out of sunlight are typically cooler. The riddle cleverly personifies sunshine, emphasizing its constant movement and the contrast it creates between light and shadow.
