I sometimes have to write for a while before I figure it out, pretend that I know what I'm doing, sort of like ad-libbing on stage until you remember your line - you hope you sound convincing to the audience. The key is to have enough material, enough threads, so that there's something that can be satisfyingly drawn to a conclusion.

Of course, I had a paradigm of a certain city in my head when I wrote these stories, a city that inspired my imagination, but it was only inspiration.

[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.

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.

The benefit of writing a collection - as opposed to a novel - is that I'm able to have some version of the war in each story without having to comment on its all-encompassing nature. Turn the page and here are new characters and new situations, but the war remains... Isn't that how life has been for us for over a decade?

The thematic links came a little later, after I noticed I was gravitating towards certain elements - war, city, weather. So it wasn't all planned out from the start, it came out of the process.

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.
