In 2004, I took a one year sabbatical to finish my second novel, A Thousand Splendid Suns. At the end of that year, I was not done with my book, and had to in effect resign from work. I did. I never went back.

I experienced Kabul with my brother the way Amir and Hassan do: long school days in the summer, kite fighting in the winter time, westerns with John Wayne at Cinema Park, big parties at our house in Wazir Akbar Khan, picnics in Paghman.

For many people in the west, Afghanistan is synonymous with the Soviet war and the Taliban. I wanted to remind people that Afghans had managed to live in peaceful anonymity for decades, that the history of the Afghans in the twentieth century has been largely pacific and harmonious.

Human behavior is messy and unpredictable and unconcerned with convenient symmetries.

You don't order someone to polish your shoes one day and call them 'sister' the next.

I entered the literary world, really, from outside. My entire background has been in sciences; I was a biology major in college, then went to medical school. I've never had any formal training in writing. So what I know about writing, I know from my own instincts, and whatever the narrative voice is in my own head.

When I was in Afghanistan in 2007, I went from village to village where refugees had returned, and they were living out in the open under tents, sometimes completely exposed to the environment. And they were homeless, which meant they would lose children in the winter to the cold and in the summers in the extreme heat. It's extremely humiliating for them to be homeless, culturally it's very shameful.
