In the story, A Wart Hog from Hell: Revelation, written by Flannery O’Connor, Mrs. Turpin is a self-righteous woman who turns on God when life takes a bad turn.
Out on the farm she screams to God, "Just who do you think you are!?"
Momentarily the question returns to her as it echoes off the mountains. She discovers her pride.
That’s what our words do. They reveal the real self. The inner person.
