"Araby" is one of a collection of 15 stories from James Joyce's collection Dubliners. This is the third of three stories told from the point of view of a young boy on the verge of adolescence. The style of narration is called first person point of view or first person narrative. Because this story is about the boy's confused feelings and emerging curiosities of adolescence, the first person point of view allows the reader to see how the young boy (narrator) thinks and feels.
Since this is a first person narration, the reader is privy to the narrator's epiphany at the end of the story. If this had been third person narration, the narrator would have had to physically describe the boy's reactions and only a third person omniscient narrator would be privy to his thoughts. With first person narration, the boy's thoughts communicate the harsh epiphany directly to the reader.
