Anton Chekhov - Misfortune

Sofya Petrovna, the wife of Lubyantsev the notary, a handsome young woman of five-and-twenty, was walking slowly along a track that had been cleared in the wood, with Ilyin, a lawyer who was spending the summer in the neighbourhood. It was five o'clock in the evening. Feathery-white masses of cloud stood overhead; patches of bright blue sky peeped out between them. The clouds stood motionless, as though they had caught in the tops of the tall old pine-trees. It was still and sultry.
Farther on, the track was crossed by a low railway embankment on which a sentinel with a gun was for some reason pacing up and down. Just beyond the embankment there was a large white church with six domes and a rusty roof.
"I did not expect to meet you here," said Sofya Petrovna, looking at the ground and prodding at the last year's leaves with the tip of her parasol, "and now I am glad we have met. I want to speak to you seriously and once for all. I beg you, Ivan Mihalovitch, if you really love and respect me, please make an end of this pursuit of me! You follow me about like a shadow, you are continually looking at me not in a nice way, making love to me, writing me strange letters, and . . . and I don't know where it's all going to end! Why, what can come of it?"
Ilyin said nothing. Sofya Petrovna walked on a few steps and continued:
"And this complete transformation in you all came about in the course of two or three weeks, after five years' friendship. I don't know you, Ivan Mihalovitch!"
Sofya Petrovna stole a glance at her companion. Screwing up his eyes, he was looking intently at the fluffy clouds. His face looked angry, ill-humoured, and preoccupied, like that of a man in pain forced to listen to nonsense.
"I wonder you don't see it yourself," Madame Lubyantsev went on, shrugging her shoulders. "You ought to realize that it's not a very nice part you are playing. I am married; I love and respect my husband. . . . I have a daughter . . . . Can you think all that means nothing? Besides, as an old friend you know my attitude to family life and my views as to the sanctity of marriage."
