Extended comment and responses in the appropriate place seem to be difficult. So I am doing it here.
To respond to Robbie's search for a definition of the short story I can only plea that in my view there is no need for one. It can be what you choose it to be. My brother Ken aka Lucas kicked off with his idea of very short stories. I picked up the ball. Lucy called them "flash fictions". Borges, the great Argentinian writer and English scholar, meanwhile, had already coined the term ficciones, fictions, to describe his pieces, almost stories if not stories. It seems to me that there is no reason not to push back frontiers. Meanwhile I am looking forward to Robbie's thoughts as promised. Only good can come of dialogue. I guess War and Peace is not a short story. Nor is Ulysses. But Borges might respond in one of his ficciones that in a different universe both might be.
Watch out for a new story in pipeline.
