The softest thing in the world

From George
While putting Gwenchik to bed:
Gwen: Do you know what the softest thing in the world is?
George: Your pillow?
Gwen: No, the sky. It's the sun's pillow, and the sun's blanket. When the sun goes to bed, the sky is what it sleeps on. Do you know when the sun gets all long and orange, just before night?
George: You mean at sunset?
Gwen: Yes. The sun gets all long because it's lying down to go to bed. And the sky is its blanket and its pillow.
