Prose Poems, Flash Fiction?

In search of a satisfactory definition of prose poems, I turned to the introduction to The Penguin Book of the Prose Poem.

Jeremy Noel-Todd writes:

"The prose poem, however, is the wittiest theorist of its own liminality, inviting us to see the ambivalence of identity as the way of the world".

Having got that cleared up (!), I've  decided to avoid such terms, and to keep to descriptions like "very short story" or "a short piece of prose".

I have just written a couple of short pieces, and some of the stories in my published collection, "This spinning world" are sufficiently short to be categorized any way one might choose.

"A story" or "prose piece" is ok by me.
