Another important aspect of writing is determining how long the story will last. It could be a day, a week, a month, a year, or several years. Writing for young kids, though, I think the time-frame should be not longer than a year. Most of the stories I write take place from one week to several months. Most important, though, is that the time-frame should match the storyline. Can a young boy save an entire world in one day? I'm not sure if that's physically possible depending upon what needs to be done. But if the writer makes the events and text seemless, then the reader will believe anything.
What sort of time-frame do you write or like to read?
