Well, if we take 'a foolish stage long story', it might be a narrative where someone is in a long - drawn - out situation that seems foolish. For example, a character who tries to build a very elaborate stage set all by himself, with no prior experience, and all his attempts end up looking really silly. But as the story progresses, he either gets help or figures out a better way on his own.
I'm not entirely sure what 'a foolish stage long story' specifically means. But perhaps it could be a story about a person who goes through a long period of being foolish on a stage, like an actor who constantly makes mistakes during rehearsals but eventually learns and grows.
Let's break it down. 'A foolish stage' could imply a situation or place that is marked by folly or lack of wisdom. 'Long story' indicates it's not a short - lived or brief event. So a possible story could be about a community that decides to hold a grand festival on a stage they build. But they make all kinds of foolish mistakes in the planning, like booking the wrong performers, having the wrong date on the posters, and so on. However, through all these mishaps, they come together, learn from their mistakes, and in the end, the festival is a huge success despite the rocky start.
