A tidy girl, dressed up for the occasion, sits by a set-up table. The doorbell rings, but the jolly young man who breaks inside holding a bottle apparently came unwanted. The photo of a completely different man's face is stuck behind the frame of the mirror in the room. The young man claims that he remembers the date of the girl's birthday, but she corrects him dryly - this birthday of hers is not the nineteenth but twentieth. The youth keeps on boasting with what pomp he himself spent his twentieth birthday. The girl briefly reminds him that at that time, he was in the army. She, however, somehow melts upon recalling how they used to build an imaginary skyscraper of love of wooden cubes, but then again turns away from the boy in indifference. The youth takes his bottle, finishes his cigarette on the polished plate on the set table and the door shuts behind him.
