The mood, also called atmosphere, has a focus that is within the setting and is constructed from the literary devices (elements and techniques) of setting, objects, descriptive details, images, diction. The mood of To Da-duh in Memoriam is youthful excitement mixed with a good deal of stubborn arrogance and brash competitiveness. After the rivalry in the story is won, the mood changes to include regret and guilt. After Da-duh's death, loss intrudes the mood.
When the nine-year-old narrator goes to Barbados to meet her grandmother, the mood responds to their sense of similarity that is rapidly sprinkle with a good deal of stubborn rivalry. On Da-duh's part, the rivalry is accompanied with a pride in her surroundings and comfortable safety that reflects in the mood, while the narrator's young arrogance adds brashness to the mood. The brashness all leaves once she wins the rivalry by humiliating her grandmother into submitting to the superiority of the urban world, which submission, incidentally, touches the story with one of its threads of irony: If the urban world wins by humiliating good women, then can it be so superior after all?
