Clouds (Object Poem)

A blanket for the blue sky.
Shapes of animals as they pass by.
Formed by water and wind
Pure white, as if no one‘d sinned.
Then white turns to grays and blacks
Rage and thunder as it attacks,
Pouring tears upon the beaten earth
Anger.  Joy. Sadness. Mirth.
Fortresses in the sky
Build and grow, by and by.
Sometimes, they seem painted
On a bright blue canvas with white untainted.
The clouds form in wisps and whirls
And dance across the sky in twirls.
