In this excerpt from "Ambush", by Tim O'Brien, the word that best helps establish the tone is C. fog. In this excerpt, the author recounts his experience when he saw the young soldier coming out of the morning fog with an ammunition belt. Without thinking, O'Brien pulled the key of the grenade, and the soldier was killed by it. Twenty years from that moment he still thinks of it and imagines the soldier passing by.
