I don't feel any ethical dilemma when I write. In my memoir, I was able to write with candor about the two most difficult people in the world to write with candor about - mom and dad. Everything else is downhill from there.

I liked the push and pull of that, between the outer political world and the inner personal lives of the characters. It's also real life... Many of us are keenly aware of world events, but break your nose and I bet that's the main thing you'd be focused on.

But it's hard for me to pinpoint where all my characters and dialogue come from - imagination or real life. My memoir, of course, was all about my past, and many of the short stories cleave very closely to my life, but the more stories I wrote in the collection, the more that seemed to be invented, but who knows... I think I'm writing about a young woman with acne who shoplifts, but I'm really writing about myself.

This is one of the ways fiction is more liberating than nonfiction - I don't have to be so concerned with fact. I had the paradigm of certain people in my head who became my characters, but I never considered these people to be from a "certain sector of society," unless we agree that we're all from certain sectors of society.

[Ending] is partly drawn from a desire to shock the audience, to brutally de-romanticize what many Americans think is happening overseas. And partly drawn from my own childhood: violence and a loss of innocence. But keep in mind that, as a writer, I'm both the criminal and the victim. I'm not trying to get out of anything easy.

I was trying to hold up a mirror to this country, to reflect the past years or so, and the varying degrees in which we've been affected by the war(s) that doesn't seem to end. And we've all been affected somehow, even if we have no connection to the military, even if we don't know anyone who's killed or been killed. No one escapes something so large.
