I feel guilty sometimes. Forty-three years old and I’m still writing war stories. My daughter Kathleen tells me it’s an obsession, that I should write about a little girl who finds a million dollars and spends it all on a Shetland pony. In a way, I guess, she’s right: I should forget it. But the thing about remembering is that you don’t forget. You take your material where you find it, which is in your life, at the intersection of past and present.
