Although I suspect it is hardly credible to say that one does not have time to write microfiction, or for that matter not even to know exactly what it is, i have been invited to join the group so here I am. I suppose a few of my terser efforts fall under the rubric.... Anyhows, as Pops used to say, I think I can collect them from time to time, and hereby offer you this, my contention being that it isn't a matter of length but of potency: "Alas," said the mouse, "the whole world is growing smaller every day. At the beginning it was so big that I was afraid, I kept running and running, and I was glad when I saw walls far away to the right and left, but these long walls have narrowed so quickly that I am in the last chamber already,
and there in the corner stands the trap that I must run into."
"You need only change your direction," said the cat, and ate it up.
Franz Kafka, as no doubt more than one of you has already guessed.
