After I had seen him repeat the same process whenever anyone was introduced to him, I realised that it was simply a social usage peculiar to his branch of the family, to which his mother, who had seen to it that he should be perfectly brought up, had moulded his limbs; he went through those motions without thinking, any more than he thought about his beautiful clothes or hair; they were a thing devoid of the moral significance which I had at first ascribed to them, a thing purely acquired like that other habit that he had of at once demanding an introduction to the family of anyone whom he knew, which had become so instinctive in him that, seeing me again the day after our talk, he fell upon me and without asking how I did begged me to make him known to my grandmother, who was with me, with the same feverish haste as if the request had been due to some instinct of self-preservation, like the act of warding off a blow, or of shutting one's eyes to avoid a stream of boiling water, without which precautions it would have been dangerous to stay where one was a moment longer.
