So far I had been travelling alone with my handbook and my Western Railway timetable: I was happiest finding my own way and did not require a liaison man. It had been my intention to stay on the train, without bothering about arriving anywhere: sight-seeing was a way of passing the time, but, as I had concluded in Istanbul, it was an activity very largely based on imaginative invention, like rehearsing your own play in stage sets from which all the actors had fled.
His action of joining them, which would have been rude in a restaurant that was not moving at three hundred kilometers an hour, was perfectly acceptable on a train, which mimicked the entirely random joinings of life but revealed their true nature by making them last only hours or days, rather than years and decades. People on a train form an alliance, as if the world that surrounded the parallel rails were hostile and and they refugees from it. The dining car, humming and rocking gently in the night, annihilated past and future and made all associations outside of itself seem vaguely unreal. So they welcomed him at their table, for he was one of them, a traveler, not one of those wraiths through whose night-lit cities they passed.
