What does a good narrative conclusion usually do?

The conclusion must wrap up the story and include what you learned or realized from this experience. It should be the logical ending to the story and be about three sentences long. Never end a paper by saying “The End!” If the reader cannot tell that the story is at an end, you need to rewrite the conclusion.
