The poem sketches a night of drinking in a few clipped, unsettling lines. It begins almost gently, with "sometimes pleased sometimes eased," as if the speaker is describing a pleasant, shifting mood. But evening arrives "by accident," which suggests a slide into drink rather than a choice. By the second stanza, the Scotch has become something that haunts and scours the house, a force that scrapes everything raw.
The last stanza is where the title makes sense. The speaker admits to a fall and to making a "disturbance," and then the poem seems to say that the noise was beaten down into the cellar. Who "her" refers to is not spelled out. It could be a person, or it could be something less literal, and the poem leaves that uncertain. What comes through is shame and a loss of control. The mood is dark and uneasy, and the short, flat phrasing makes the confession feel more chilling, as though the speaker can only report what happened, not explain it.
