I hate it when a short story will be mostly descriptive until the last page or so. Then there will suddenly be a story which will usually involve the main character getting killed somehow.
I've read dozens of stories like this, and the number would probably be much higher if I read more short stories. This always seems like a desperate move to me. The author is just trying to sneak in a story because it's supposed to be there.
Keep this in mind, you can write a story that's descriptions and imagery, or you can write a story that has an interesting narrative, but you really can't mix the two. This is something I would teach my students if I ever got to teach writing again.
