Narrative writing is a style of writing that tells a story. It can be fiction or nonfiction, and it can take many different forms, such as novels, short stories, essays, memoirs, and autobiographies.
An autobiography is a written account of a person's life, written by that person. It is a type of nonfiction narrative writing, as it tells the story of the author's life in a chronological order. Autobiographies often include details about the author's childhood, education, career, and personal life.
