John McCain may have done some heroic things, but he is a hero no more. Imagine how you’d feel. A knock on your door. Through the deadlights around your front door, you see a car with government stencils on the side. When you get close enough, you look out and see a man in uniform. An officer. You know. You know why he’s here. Your throat tightens. You want to turn around and walk away. You can’t. You must open the door. You must let this officer recite his grim script.
