The author narrates the story from a third-person point of view. Despite this fact, the grandmother is in focus almost all the time. The narrator reveals her trail of thoughts to deliver the message of the story.
Detailed answer:
The point of view in A Good Man Is Hard to Find contributes to the author’s storytelling style. For an unreliable narrator, it is acceptable to exclude some unimportant descriptions. The author uses a narrator with limited omniscience. All the events appear from the grandmother’s point of view. Still, the point of view is not limited to her vision.
The point of view relies on foreshadowing and symbolism. But it would be impossible to incorporate them without a limited omniscient narrator. They place The Misfit in the story prior to his actual appearance. Symbolism includes a shift in the point of view, which occurs when the car hits the ditch.
The chosen way of narration allowed O’Connor to place the focus on a single character. Meanwhile, she avoids making the reader too attached to the grandmother. The setting allows the author not to go into detail about the grandmother’s family. By doing so, she makes them less essential for the plot. The narrator can avoid mentioning their point of view and focus solely on the grandmother’s story.
