They talked long, and it was late when Lukashka, not tipsy (he never was tipsy) but having drunk a good deal, left Olenin after shaking hands.
Olenin looked out of the window to see what he would do.

Lukashka went out, hanging his head.

Then, having led the horse out of the gate, he suddenly shook his head, threw the reins of the halter over its head, sprang onto its back like a cat, gave a wild shout, and galloped down the street.

Olenin expected that Lukishka would go to share his joy with Maryanka, but though he did not do so Olenin still felt his soul more at ease than ever before in his life.

He was as delighted as a boy, and could not refrain from telling Vanyusha not only that he had given Lukashka the horse, but also why he had done it, as well as his new theory of happiness.
