At first, on that first journey out of the city into India, I found such sudden politeness infuriating after the violent scramble to board the train. It seemed hypocritical for them to show such deferential concern over a nudge with a foot when, minutes before, they'd all but pushed one another out of the windows. Now, long years and many journeys after that first ride on a crowded rural train, I know that the scrambled fighting and courteous deference were both expressions of the one philosophy: the doctrine of necessity. The amount of force and violence necessary to board the train, for example, was no less and no more than the amount of politeness and consideration necessary to ensure that the cramped journey was as pleasant as possible afterwards. What is necessary? That was the unspoken but implied and unavoidable question everywhere in India. When I understood that, a great many of the characteristically perplexing aspects of public life became comprehensible: from the acceptance of sprawling slums by city authorities, to the freedom that cows had to roam at random in the midst of traffic; from the toleration of beggars on the streets, to the concatenate complexity of the bureaucracies; and from the gorgeous, unashamed escapism of Bollywood movies, to the accommodation of hundreds of thousands of refugees from Tibet, Iran, Afghanistan, Africa, and Bangladesh, in a country that was already too crowded with sorrows and needs of its own. The real hypocrisy, I came to realise, was in the eyes and minds and criticisms of those who came from lands of plenty, where no-one had to fight for a seat on a train. Even on that first train ride, I knew in my heart that Didier had been right when he'd compared India and its billion souls to France. I had an intuition, echoing his thought, that if there were a billion Frenchmen or Australians or Americans living in such a small space, the fighting to board the train would be much more, and the courtesy afterwards much less.
