Clouds -- fiction
In Cloudette, by Tom Lichtenheld, a smaller than average cloud is happy and well-adjusted to her life in the sky. Being small gives her all sorts of advantages such as cute nicknames, great hiding places and the best view of the fireworks. But when the big clouds sail off to create storms and to water the fields, Cloudette gets the urge to do something big and important, too. So off she goes to find a job.
