When accepting a writing prompt an author gets a brief glimpse, a flash, into a world that must be explored. It is something akin to a snow plough passing a window in the night. The world is strange and muffled, the details are fuzzy and indistinct. The author must in the privacy of their own mind determine what the details of the story are. Fortunately, unlike a psychic who is required to be uniform and realistic, the fact that every author can create a completely different story from the same picture is not only accepted but celebrated.
So my publisher says that every fourth post should promote my book....I am sure there are clever and subtle ways to do that. I will learn them some day.
