An author can use the narrative style when writing a personal essay, while anything can be described - from the worst day of your life to how you ran your first marathon. Often it becomes clear that a writer is analyzing material, letting events sift in his mind, trying to make sense of something. A personal essay is often a way of working things out, and by the end, the writer and reader should understand that something has indeed been worked out. Endings do not need to be wrapped up in a tight and seamless manner, and sometimes events don't make sense. However, there still needs to be an ending or resolution to the incident.
