i like to cloud watch.
i once was waiting at a car service station to get my oil changed when the manager came up to tell me it would take a while. he pointed to this box on the counter and said, "if you've got the time, you might as well write a letter to our troops." i normally don't do things like that, but i took a card and wrote, "i'm looking up at the sky in charleston, south carolina and the clouds are big and puffy. the kind that take up the whole sky." and dropped it in the box.
i don't know what sparked that memory, after all these years. perhaps it was, "what to write about clouds..." :)
