Lahore, the second largest city of Pakistan, ancient capital of the Punjab, home to nearly as many people as New York, layered like a sedimentary plain with the accreted history of invaders from the Aryans to the Mongols to the British.

I am a strong believer in the intertwined nature of the personal and the political; I think they move together.

And I ask myself what it is about me that makes this wonderful, beautiful woman return. Is it because I'm pathetic, helpless in my current state, completely dependent on her? Or is it my sense of humour, my willingness to tease her, to joke my way into painful, secret places? Do I help her understand herself? Do I make her happy? Do I do something for her that her husband and son can't do? Has she fallen in love with me? As the days pass and I continue to heal, my body knitting itself back together, I begin to allow myself to think that she has.

I think writing is a very political act. I think that any writer who says it's not, is simply a writer who is disavowing the political connotations of what they write.

We are all refugees from our childhoods. And so we turn, among other things, to stories. To write a story, to read a story, is to be a refugee from the state of refugees. Writers and readers seek a solution to the problem that time passes, that those who have gone are gone and those who will go, which is to say every one of us, will go. For there was a moment when anything was possible. And there will be a moment when nothing is possible. But in between we can create.

I think we should be prepared, given environmental and political change for large-scale migration. If sea levels rise and 200 million people in Bangladesh and 300 million people in Indonesia need to move, and the entire Chinese seaboard, New York City - that's going to be huge.

Which is stronger, politics or love? is like asking, Which is stronger, exhaling or inhaling? They are two sides of the same thing.
