What effect is produced by the difference in age between narrator-as-charactor and narrator-as-storyteller?The age of the narrator at the time of the story and when he tells the story.
Often in this structure, the mature voice of the narrator comments on the action as it occurs; an example of this is the narrative device in To Kill a Mockingbird, where the older Scout constantly interprets events for us as the younger Scout enacts them. In "Araby," the narrator does not interpret as the story proceeds. He recounts the events compassionately, but never saying as the story develops something such as "I was a romantic fool, young and innocent, not knowing the ways of the world," which is what we understand by the end of the story. Indeed, even at the end of the story he does not explain and interpret but again "shows" (rather than "tell"s and reflects upon) what the character learns: his eyes "burned with anguish." This strategy of "showing" heightens drama and preserves complexity, too, for the narrator has a more demanding responsibilit to relate events through symbols and motifs--these carry a great weight in understanding "Araby."
