It must not be forgotten also that by this time he had become convinced of the complete uselessness, even undesirability, of his remaining longer with Sofya Andreyevna, and that therefore the various impulses to go away which he had before so scrupulously repressed in his soul were now set free. The painful consciousness of luxury and privilege in which his life was spent in the midst of the poverty around him, the yearning for peace and solitude before death, and many other causes began without hindrance to impel him in the same direction. Thus the cup was already full and only the last drop was lacking. And just at this time suddenly the new element in his wife's behaviour which provided that last impulse to departure was revealed to Leo Nikolaevitch. What was new to him was the sudden revelation of the atmosphere of lying and hypocrisy in which he saw himself entangled. He unexpectedly became the involuntary witness of how Sofya Andreyevna, when she thought he was asleep, secretly stole up to his papers, and of how, as soon as she found out that he was not asleep, she began again at once as though nothing were the matter, expressing solicitude for his health. His eyes were at once opened and he saw what had long been well known to his intimate friends, but what the remnant of confidence in and respect for his wife which were still preserved in his soul, forbade him even to admit in his thoughts: that is, that _she was acting a farce with him_. Together with this discovery everything was transformed for Leo Nikolaevitch, and indeed that was inevitable. It was of little moment that the incident which opened his eyes may seem in itself not to be of much importance. For married people who have lived together fifty years the first incident which reveals hypocrisy in one of them is always of importance. This incident at once threw quite a new light for Leo Nikolaevitch on all that had passed between him and Sofya Andreyevna. Till that time he had supposed that he had to do with sincere egoism and ill-will, with open wilfulness and innate coarseness and with morbid abnormality. And meeting this with unvarying mildness, patience and love, he recognised that he was doing as he ought, and therefore felt an inner satisfaction. Now all this was turned upside down. In the past the position had been clear; before him was a definite evil which laid on him as definite a duty to meet the evil with good. Now he had to do with a sort of tangle in which there was so much falsity that it was impossible to make out where reality ended and deception began; so that instead of his former satisfaction Leo Nikolaevitch suddenly felt the ambiguous position in which he found himself. So at least I explain to myself the extreme emotion which Leo Nikolaevitch felt at his final decision to go away.
