The poem moves between three scenes, and the gaps between them do much of the work. First we get a public execution, described in flat, almost note-like phrases: a general hanged, drawn and quartered, his head and heart displayed. The line about "great shouts of joy" heading "to the Lord" is chilling, since the crowd's celebration is tied to religious comfort. Then the setting shifts to home, where the speaker, angry with his wife, kicks a basket he had bought her and breaks it. It's a small, petty act, but the poem states it without excuse.
The last line, "All afternoon setting up shelves," is quiet and practical. The speaker doesn't say what he feels, but the placing of these scenes suggests a sense of shame, or an attempt to repair and put things in order. The mood is subdued and uneasy, as if ordinary domestic anger and public cruelty are less far apart than we'd like to think.
