The poem moves from a comic scene to a stranger, more magical one. In a tenement lobby, a heavy-footed man pounds out a Chopin nocturne, and the speaker's mockery is plain: he is a power hammer in a nursery, butchering delicate music. When a little girl named Natalia asks him to take a break, she plays the piece beautifully herself.
Then the poem lifts upward to her apartment, where Necessity, a personified figure, seems to be the same woman as Natalia's grown-up counterpart or perhaps a larger idea behind her. Her home is a crowded curiosity shop, and she runs a pirate radio station that broadcasts only silence, kept by two children building villages. In the end she carries a wasp nest into the elevator, and the rat and the collection agent, symbols of the building's threats, turn meek and polite.
The mood is playful, offbeat, and affectionate. The speaker seems to admire resourcefulness: poverty doesn't mean poor imagination, and quiet, odd strength can beat noise and greed.
