3. When she heard of this, Olga Dmitrievna affected to be very much alarmed; she began to be affectionate to her husband, and kept assuring him that it would be cold and dull in the Crimea, and that he had much better go to Nice, and that she would go with him, and there would nurse him, look after him, take care of him.
4. Now, he understood why his wife was so particularly anxious to go to Nice: her Michel lived at Monte Carlo.
5. He pictured the pitiable, ludicrous part he would play if he had agreed to go to Nice with his wife.
6. He remembered how in his father's house in the village a bird would sometimes chance to fly in from the open air into the house and would struggle desperately against the window-panes and upset things; so this woman from a class utterly alien to him had flown into his life and made complete havoc of it.
7. The best years of his life had been spent as though in hell, his hopes for happiness shattered and turned into a mockery, his health gone, his rooms as vulgar in their atmosphere as a cocotte's, and of the ten thousand he earned every year he could never save ten roubles to send his old mother in the village, and his debts were already about fifteen thousand.

18. And what's more, if you care to know, I'm not certain that my feeling will last long . . . so there! I'm not going to leave you."
19. And Nikolay Yevgrafitch himself in the photograph looked such a guileless soul, such a kindly, good fellow, so open and simple-hearted; his whole face was relaxed in the naïve, good-natured smile of a divinity student, and he had had the simplicity to believe that that company of beasts of prey into which destiny had chanced to thrust him would give him romance and happiness and all he had dreamed of when as a student he used to sing the song "Youth is wasted, life is nought, when the heart is cold and loveless."
