Linda, it is a bit more difficult to make a story in 55 words than one might think. One is tempted to stretch it to 75 or 100 or 125 words. But that is the discipline -- stick to a limit, whatever that is. Write a lot more words, to get the idea down, and then start cutting and combining, using "You're" in place of "You are", etc.., etc. My "Nevertheless" was a similiar exercise in making a "complete story", with almost every sentence relating to a time in the protagonist's life from before birth to the death bed. I'm not sure I succeeded with that.
Somewhere I read that the briefest story was, "He was born. He lived. He died." Not a very compelling read, huh? Fill in the blanks. In a way, that is what we have to do: "It began with this, then this happened, then this was the result." We must ask ourselves, "Why am I telling this story? Why am I starting here? How does this story end? What happens to cause that end of the story?"
I know that my stream of consciousness, which my muse jump starts, does not give me those answers. Therein, is the work of the writer. For some reason, right now I am reminded of the poem by Emile Dickenson: "Tell all the truth, but tell it slant. Success in circuit lies. Too bright for our infirm delight The truth's superb surprise. As lightning to the children eased With explanation kind, The truth must dazzle gradually, or every man be blind."
I wonder, who am I to think that I might have something equally inspirational to offer?
