The Unforgiving Middle

No, not my unforgiving middle, although after a few days of Cindy's birthday cake, my middle is also quite unforgiving. It's the middle of my current story that's unforgiving. I'm very pleased with the story's opening (slightly over 1000 words) and have a pretty good idea of how the story will end, but the middle could go in several different directions. Could be that I'm afraid the middle might lead me to a different ending, which might not be a bad thing. We shall see.
