I don't want you to think that I'm being willfully obtuse, but I've never really grasped how point of view could be regarded as a matter of choice independent of story. Point of view is intimately interwoven into the story that you want to tell - it is an aspect of it.

Of course, an English aristocrat might have some contact with the staff downstairs and could adequately say a thing or two about inter-class dramas unfolding in the household. But something less parochial might be harder to come by. This is relevant because stories about the divisiveness of class are by definition stories that straddle class boundaries. A story about a miner in a mining town is not obviously one that speaks to the divisiveness of class. In other words, class doesn't just divide us in the world but it also divides us in the stories we're presented.

Our interaction with our friends, for instance, is in large part an interaction with representations in our own head of the people before us. That's why a friend can surprise or disappoint us.

I had an indefatigable curiosity about everything. But why should my fate have depended upon that? Why does the curiosity of a child born into the lowest classes have to overcome everything put in his or her way to mute that curiosity, when a child born to parents with access to the advantages of life will have his meager curiosity kindled and nurtured? The unfairness is horrifying when it is properly understood as an unfairness meted out on children, on infants, on babies.

I had a tough childhood, yes. I was born in rural Bangladesh to parents who had had no education beyond high school. We moved to the UK where I grew up in poverty, in some of the worst conditions in a developed economy, before moving to the projects - heaven - and I went to unremarkable schools before going to university. My father was a bus conductor first and then a waiter, and my mother a seamstress.

I am at my happiest when I'm problem solving and a large part of writing is for me a lovely labor in problem solving. Every act of discovery in writing involves a process of figuring out why I'm not seeing what I need to see. Niggling feelings, discomforts, a sense that you've forgotten or overlooked something, a sudden curiosity about what if here? - these are priceless. They are the bases of problems and lead the way.

Novels need readers of a certain kind, people who are patient and enjoy immersing themselves in another perspective for uninterrupted stretches of time. Reading habits might well be changing. People who pay for novels might overlap significantly with those who engage in Twitter and Facebook.
