Vronsky lives in a spacious Finnish cottage with Petritsky now that the regiment is out in the country.
Yashvin prods Petritsky with a toe and wakes up the man. Petritsky is suffering the consequences of having drunk too much the night before.
According to Petritsky, Vronsky's older brother called on him.
Petritsky is cranky and has a bad taste in his mouth. Yashvin suggests drinking some vodka. Petritsky tries to get everyone else to drink with him. Finally he remembers that Vronsky's brother left a letter. He tries to remember where he left it, and finally locates the letter.
In the letter, both Vronsky's brother and mother complain. His mother complains that Vronsky hasn't come to see her, and his brother says that he wants to talk to Vronsky.
Vronsky leaves to inspect his racehorse (and see Anna). Also, he's avoiding drinking because he doesn't want to add to his weight before the races.
On his way out, some officers make fun of his premature baldness.
