A recurring theme in The Things They Carried is the investigation and problematization of ideas such as courage, heroism, and valor. In this vignette, O'Brien again takes up the notion of memory and makes us question how we honor the memory of war and war heroes. The opening line of the story immediately confronts us with paradox: "When Curt Lemon was killed, I found it hard to mourn." We expect someone to mourn a fallen comrade, especially a fellow soldier, but O'Brien will not because, he leads us to believe, Curt Lemon did not earn the right to be mourned. So then, we must ask what must someone do in order to be mourned? In response, O'Brien gives us the story of Lemon and the Army dentist, giving his audience the opportunity to judge whether Lemon deserves mourning or not.
The story of Lemon and the dentist is a simple one with complex implications. Lemon is a braggart and relishes creating a machismo personality. His weakness is that he needs others to hold him in awe, to treat him as important. It is upon this weakness, as O'Brien sees it, that the story pivots and O'Brien's low opinion of Lemon is based.
The setting is a relaxed environment that comes close to the description of a vacation. There is no impending fear, no looming threat of attack, and in this setting Lemon finds himself out of sorts. As O'Brien frequently does, he makes the appearance of the dentist a seemingly random event, denying us the ability to find constant meaning in the war and its mechanisms. Lemon is shown not to be high strung or brave, but childish, reverting to fears sustained as a child about dentists. These fears overpower him even as an adult, a man, a soldier. So potent are the fears of youth that they can weaken even the man who tries harder than anyone to appear strong. Lemon does not even fight against seeing the dentist, but instead faints and quietly is carried away.
