I write as someone who has no more time for repressive Islam than he does for repressive Christianity or Judaism, but at least look at the face in the hijab - and try to imagine the one beneath the niqab - before you depersonalise its wearer.
I am a regular, if not exactly enthusiastic, patron of my local bookshop. I try to buy at least some books there because I cling to the belief that it's important to maintain those businesses which put a human face on the exchange of money for goods and services.
Continuous present is all we have, and stream of consciousness - which in a novel is arguably just as artificial as the stilted dialogue that you get in most conventional novels. They're all stratagems to try to get closer to the texture of lived life.
