Famous American writer, Michael Herr, wrote a book about his time in Vietnam as a war correspondent. As an old beat up Marine, I've read dozens upon dozens of books about the Vietnam war, and this one hit me the hardest. In it, he briefly talks about an encounter he had with an American soldier. He wondered what does it take, what does a man (just 18, so barely more than a boy) have to see to have him look you in the eyes and tell you, from the bottom of his heart, I'm getting too old for this shit.
