I drabble, though technically, since drabble's a noun, I guess I should say I write drabbles.
Wikipedia defines a drabble as “an extremely short work of fiction exactly one hundred words in length…” So why drabble?
A short work of fiction is still a story, of course, with beginning, middle and end. Every scene’s important, though there’s probably only one, so select it well. Every word has to count and repetitions look bad. Every detail reveals character or forwards plot, or else gets deleted.
There’s no room for waste in a drabble. I drabble daily. And then I write novels.
