In just three short lines, this poem sets two worlds side by side. The first is an office crowded with clerks, a place the speaker describes mainly by what it lacks: "no quiet." Noise and busyness fill the room, and there is nowhere to rest the mind. Then the last line turns away. The speaker gazes on swans, and the shift feels like a long, slow exhale.
The title, "Inspirational poster," adds a wry twist. It suggests the swans may not be real at all. Judging by the title, they could be a picture on the wall, the kind of calm image offices hang to cheer people up. If so, the speaker is escaping into a mass-produced scrap of beauty because nothing else is on offer.
The mood is quietly humorous and a little wistful. The speaker feels hemmed in and tired of the din, yet the gesture of looking at the swans is also tender. It shows how a small image can give someone a moment of peace.
