There was absolutely no way Ian Smith was suffering from posttraumatic stress disorder. He was sure of it.
He was O.K. He was living with his girlfriend in a suburb of Nashville working three jobs -- mowing lawns, delivering pizzas, cleaning a local church. He was carrying a 4.0 average at Volunteer State Community College. Yes, he'd seen some terrible stuff during two tours in Iraq. But others had been through much worse. He'd never been wounded. He was alive.
