The Biographical Theory is the most useful literary theory that sheds light on both stories.
The Biographical Theory helps the reader to evaluate how the authors' life and experiences inform their stories.
For example, Flannery O'Connor, in "The Life You Save May Be Your Own," expresses the difficulty in getting a good man to marry.
Using the Biographical theory, one can appreciate William Faulkner's "A Rose for Emily," which chronicles the life of this unmarried townsfolk, who ended up murdering the one husband she married.
Faulkner uses his fictional town as the setting for the book, making a critic to suggest that the fictional incident actually takes place in Faulkner's town, and therefore, is reflective of his life experiences.

Â A good look shows that the stories are not focused on historical and gender issues. Â Instead, the stories portray how the life and experiences of the authors influence their writings.
