How did the narrator express the theme of "Thank You, Ma'am" through the point of view?

Langston Hughes's "Thank You, Ma'am" is told from an
omniscient, third-person point of view. The point of view is important in the story
because it allows us to see different elements from both Mrs. Jones's and Roger's
perspectives, without getting too close to either one. This is important because it
greatly helps to build the suspense of the story as we question what punishment Mrs.
Jones might exact on Roger. That suspense, then, reinforces the central themes of the
story--compassion, second chances, forgiveness. We keep anticipating that the punishment
will be delivered in part because we are not "inside the head" of either Roger or Mrs.
Jones. But no punishment is ever given, only forgiveness.
