Vronsky stood still and asked directly

Vronsky stood still and asked directly: "How so? Do you mean he made your belle-soeur an offer yesterday?"
"Maybe," said Stepan Arkadyevitch. "I fancied something of the sort yesterday. Yes, if he went away early, and was out of humor too, it must mean it.... He's been so long in love, and I'm very sorry for him."
"So that's it! I should imagine, though, she might reckon on a better match," said Vronsky, drawing himself up and walking about again, "though I don't know him, of course," he added. "Yes, that is a hateful position! That's why most fellows prefer to have to do with Klaras. If you don't succeed with them it only proves that you've not enough cash, but in this case one's dignity's at stake. But here's the train."
The engine had already whistled in the distance. A few instants later the platform was quivering, and with puffs of steam hanging low in the air from the frost, the engine rolled up, with the lever of the middle wheel rhythmically moving up and down, and the stooping figure of the engine-driver covered with frost. Behind the tender, setting the platform more and more slowly swaying, came the luggage van with a dog whining in it. At last the passenger carriages rolled in, oscillating before coming to a standstill.
A smart guard jumped out, giving a whistle, and after him one by one the impatient passengers began to get down: an officer of the guards, holding himself erect, and looking severely about him; a nimble little merchant with a satchel, smiling gaily; a peasant with a sack over his shoulder.
Vronsky, standing beside Oblonsky, watched the carriages and the passengers, totally oblivious of his mother. What he had just heard about Kitty excited and delighted him. Unconsciously he arched his chest, and his eyes flashed. He felt himself a conqueror.
"Countess Vronskaya is in that compartment," said the smart guard, going up to Vronsky.
The guard's words roused him, and forced him to think of his mother and his approaching meeting with her. He did not in his heart respect his mother, and without acknowledging it to himself, he did not love her, though in accordance with the ideas of the set in which he lived, and with his own education, he could not have conceived of any behavior to his mother not in the highest degree respectful and obedient, and the more externally obedient and respectful his behavior, the less in his heart he respected and loved her.
