Part of the reason I'm writing it is to try to figure out what that is myself. It's not like I came back from Iraq and said, "We need to have a conversation, I know exactly what it is." It was just this sort of sense of something missing and then trying to write toward what that was, and to solicit from other people a sense of what that might be.

There are two ways to tell the story. Funny or sad. Guys like it funny, with lots of gore and a grin on your face when you get to the end. Girls like it sad, with a thousand-yard stare out to the distance as you gaze upon the horrors of war they can't quite see. Either way, it's the same story.

And that was my homecoming. It was fine, I guess. Getting back feels like your first breath after nearly drowning. Even if it hurts, it's good.

The part of the strangeness of coming back from the war is the way we talk about it. We try to have a discussion about the war that doesn't turn into a discussion about one political side or the other. I wanted to reach out and talk to people about it through fiction, the way a narrative can draw someone in and ask them those questions.

Sin is a lonely thing, a worm wrapped around the soul, shielding it from love, from joy, from communion with fellow men and with God. The sense that I am alone, that none can hear me, none can understand, that no one answers my cries, it is a sickness over which, to borrow from Bernanos, “the vast tide of divine love, that sea of living, roaring flame which gave birth to all things, passes vainly.” Your job, it seems, would be to find a crack through which some sort of communication can be made, one soul to another.

It's not so much the question that offends me; it's that the people asking it don't seem to respect the moral seriousness of the question.
