In "Good Form" O'Brien explains up what he has been trying to communicate about the difference between the plot and the theme. Norman Bowker felt responsible. Jimmy Cross felt responsible. Azar did. And so does O'Brien. We all should. "For instance, I want to tell you this: twenty years ago I watched a man die on a trail near the village of My Khe. I did not kill him. But I was present, you see, and my presence was enough."
