The speaker is addressing someone who has gone, or is about to go, and trying to work out why. The opening is gentle and a little anxious: "I worry you find jasmine too sickly a scent." Jasmine is usually a loved smell, so the worry suggests the speaker is afraid that something sweet to them was cloying to the other person. The blossom becomes "a burden," and the sweeping each morning turns a pretty thing into a chore.
The second stanza lists small complaints: loud birds, out of tune. The phrase "of course" gives it a dry, slightly wounded edge, as if the speaker is quietly mocking the reasons while still accepting them. Then comes the plain conclusion that "Petushki wasn't for you." The poem never names a bigger grievance, which is what makes it sad. Petushki appears to be a place, though the poem doesn't say more. The mood is wistful and restrained, with hurt tucked beneath small, domestic details.
