The narrator is an older Tom, some years after the scenes that are played out. He defines the way in which the play is presented here, as a "memory scene." Not only does the narrator guide us through the action with, you know, narration, but he also infuses the play with its tone and memory-like appearance. Because we hear the story from the guy in the story, we know it has been altered and adjusted. The point of view, then, becomes hugely important when we consider that objectivity, and potentially accuracy as well, have been removed from this story.
