The Tale Of Mr. Peter Brown - Chelsea Justice / From "The New Decameron", Volume III.

THE first thing which attracted my attention to the man was the shock of white hair above the lean young face. But for this, I should not have looked twice at him: long, spare, and stooping, a shabby figure, he crouched over a cup of coffee in a corner of the dingy restaurant, at fretful enmity with the world; typical, I should have said, of the furtive London nondescript. But that white hair startled me; it gleamed out, unnaturally cleanly in those not overclean surroundings, and although I had propped my book up against the water-bottle at my own table, where I sat over my solitary dinner, I found my eyes straying from the printed page to the human face which gave the promise of greater interest. Before very long he became conscious of my glances, and returned them when he thought I was not observing him. Inevitably, however, the moment came when our eyes met. We both looked away as though taken in fault, but when, having finished his coffee and laid out the coppers in payment on his table, he rose to make his way out between the tables, he let his gaze dwell on me as he passed; let it dwell on me quite perceptibly, quite definitely, with an air of curious speculation, a hesitation, almost an appeal, and I thought he was about to speak, but instead of that he crushed his hat, an old black wideawake, down over his strange white hair, and hurrying resolutely on towards the swing-doors of the restaurant, he passed out and was lost in the London night.
I was uncomfortably haunted, after that evening, by a sense of guilt. I was quite certain, with unjustifiable certainty born of instinct, that the man had wanted to speak to me, and that the smallest response on my part would have encouraged him to do so. Why hadn't I given the response? A smile would have sufficed; a smile wasn't much to demand by one human being of another. I thought it very pitiable that the conventions of our social system should persuade one to withhold so small a thing from a fellow-creature who, perhaps, stood in need of it. That smile, which I might have given, but had withheld, became for me a sort of symbol. I grew superstitious about it; built up around it all kinds of extravagant ideas; pictured to myself the splash of a body into the river; and then, recovering my sense of proportion, told myself that one really couldn't go about London smiling at people. Yet I didn't get the man's face out of my head. It was not only the white hair that had made an impression on my mind, but the unhappy eyes, the timidly beseeching look. The man was lonely, I was quite sure of that; utterly lonely. And I had refused a smile.
