Natasha had made a strong impression on Kuragin. At supper after the opera he described to Dolokhov with the air of a connoisseur the attractions of her arms, shoulders, feet, and hair and expressed his intention of making love to her. Anatole had no notion and was incapable of considering what might come of such love-making, as he never had any notion of the outcome of any of his actions.

"She's first-rate, my dear fellow, but not for us," replied Dolokhov.

"I will tell my sister to ask her to dinner," said Anatole. "Eh?"

"You'd better wait till she's married...."

"You know, I adore little girls, they lose their heads at once," pursued Anatole.

"You have been caught once already by a 'little girl,'" said Dolokhov who knew of Kuragin's marriage. "Take care!"

"Well, that can't happen twice! Eh?" said Anatole, with a good-humored laugh.
