"Notes" is the key vignette for unlocking the medium-is-the-message form of O'Brien's novel. Just as the title indicates, in this chapter "O'Brien" offers commentary, or notes, on how the preceding chapter, and more generally, the novel, was conceived and shaped into its final form. Again O'Brien returns to the novel's overarching theme of the relation between fact and fiction and the "truthfulness" inherent in stories that are not necessarily "actual" or "factual."
Though readers can easily mistake the protagonist "Tim O'Brien" for the actual novelist, readers must keep this divide in mind to fully understand this chapter, or the novel as a whole. The most important aspect of the chapter is the description of the process through which the fictional "O'Brien," a middle-aged writer, turns the stuff of memory into stories. In so doing, O'Brien collapses boundaries between the two genres that The Things They Carried occupies: the ("fictional") war autobiography of "Tim O'Brien" and the ("fictional") writer's memoir of "Tim O'Brien."
By walking the reader through the genesis of "Speaking of Courage," O'Brien more thoroughly comments on the running thread of the theme of storytelling. The protagonist "O'Brien" compares himself to Norman Bowker, commenting that he, too, rarely spoke of the war, but that he "had been talking about it virtually non-stop through [his] writing." His writing was a way to issue meaning to the random events that had occurred to him, an ability that Norman Bowker badly needed but did not possess. Bowker looked to "O'Brien" to articulate the feeling of loss that Kiowa's death brought him. "O'Brien's" multiple versions of the story of Kiowa's death stand in contrast to Bowker's; Bowker's is an extremely subjective account, one which claims vast culpability and has the dire result of suicide, the ultimate subjective act. On the other hand, O'Brien outlines the usefulness of storytelling because it allows "you to objectify your own experience." This storytelling ability is exactly what Norman Bowker is incapable of, and also what affords "O'Brien" the vantage, first, to tell the story Norman cannot and, second, to use that story to better understand himself. O'Brien achieves this by describing the landscape "O'Brien" placed in the "Speaking of Courage" vignette: "O'Brien" transplants the details of his native Minnesota to Norman Bowker's Iowa.
