(The story of how day turns to night)
It's like the sun is trying to escape, but it's stuck between the mountains and the clouds. It just wants to rest, pass the horizon and sleep, but it is stuck.
The clouds, moving quicker than they appear, are hurrying to follow the sun for they are the sun's disciples. They make way for the stars which are the disciples of the moon.
While the clouds paint a fluffy picture that is hard to make out, the stars perform beautiful plays as they dance across the sky.
The sun is almost gone, a dwindling sparkle of a light, and the clouds are all following to make way for the night.
