I sent the castle story today. At the last moment, I recognised one of its problems, but had no time to fix it. (A sign of a lazy writer, undeserving of any success!)
The story is about things that happen to my main character. Although her character develops, and she learns from her experience (as much as is possible in 1600 words) she doesn't fix the problem herself. I think I've set that up well enough...but I'm not sure.
