For Cafelit I usually write 100 words short stories. For other sites (usually competition entries) I write between 250 and 750 words. But the challenge is for the stories to make sense and for them to read as if you couldn't possibly leave another word out.
Flash fiction, for a writer, is the ultimate in "short but sweet". I find proverbs can make great titles and be wonderful inspiration for very short work. One new flash fiction piece of mine is:-
THE CIRCLE OF LIFE
People throw kittens into the river here. I hate that. It’s so cruel. What can I do?
I thought I’d rescue the poor animals but they’d only be thrown in again when I’m not about. I know my people. Subtle they are not.
So I decide to create a need for cats. If people need them they won’t drown them so the kitties win as well. How to do this? Easy peasy.
Get all the mice I can find and unleash them on the village! I’ll be setting the first lot free at dawn.
