Humilis

The cumulus clouds hover steady
and low in the evening sky.
They are blue or white. Their choice.
They don’t need to give a reason.
Blue because they want to;
white because they feel like it.
When they’re ready to
roll their own die, they shake
out to sea, join other clouds,
frustrate the surf with rain, and
contemplate the breeze
in another life, as sand.
