Good stories aren’t just beginning, middle, and ending, and entertaining. That’s fine, those are of value. But a good story haunts you for a while. There’s something in there you want to keep thinking about and maybe go back to that story again. That’s what I think a good writer should do: keep haunting the reader for a while, about what you’re saying, about how or why, so that the reader says, “I can’t just let it go.”
