An autobiography is a personal narrative where an individual recounts their own life experiences, often including various mundane elements that might not seem interesting to others. It serves as a reflection of their journey, capturing both significant milestones and everyday moments that shaped their identity. In this context, the author aims to provide an honest portrayal of their life.

In "Boy: Tales of Childhood," Roald Dahl emphasizes that while autobiographies can be filled with seemingly dull details, these aspects are vital to understanding the person behind the story. He suggests that even the commonplace elements contribute to the richness of one's life narrative, making it both personal and relatable.
