An essay should have a clear theme or make a clear claim. While narrative essays aren't focused on evidence for claims, the story should still have a point. The thesis statement tells readers what the point is and/or sets the scene for the body of essay. The thesis statement highlights a lesson learned, sets the scene, or identifies a theme. The thesis statement is generally found at the end of the introductory paragraphs and helps readers understand the direction your essay will take. It introduces the story or action that is about to begin.
