The narrator's letters act neither as "chatty" correspondence nor as a narrative device that substitutes for conventional expository narration but could just as easily be replaced with some other device that gets the story told. The narrator's halting, circuitous language emphasizes its own unfolding as language, working to ensure that we are always as aware of this language as we are the story it is struggling to move along. The narrator is struggling with the story, and the manner of telling reinforces that struggle. Perhaps we could say that this method is "poetic," not so much because more often than not language is laid out on the page in a compressed way that seems "verse-like" but because it does stress so concertedly the effort to find efficacious expression of what one wants to say, to find the right means and medium.
