Three short lines create a picture of late autumn emptiness. Leaves have been blown away; birds have flown. The speaker wanders “in and out” of the Hall of Autumn, as if moving restlessly through a place stripped of life and sound. The hall may be a real building, but it also feels like a state of mind—an open, echoing season of loss.
The mood is quiet and solitary, not violent or dramatic. There is no one else, no birdsong, no rustling leaves. The speaker seems to feel a mix of loneliness and calm, left with only movement through empty space. “Autumn” here suggests a turning point, the end of warmth and growth. The repeated absence—blown leaves, flown birds—makes the wandering feel both aimless and meditative, as if the speaker is keeping company with change and letting it pass.
