The speaker begins with a small loss: an appetite that vanished before supper, just as a strict grandmother once warned would happen if children ate sweets. From there the memory drifts to another grandmother, who lit a cigarette and sent the kids outside so the adults could enjoy their cocktail hour in peace. That moment of being shooed away becomes the poem's turning point, and the speaker imagines dissolving into a yellow field full of bees.
After that, the poem leans on image rather than story. Yellow spreads like plants cracking open stone, filling the space where hunger used to be. By sundown the speaker stands in the middle of it, still and a little out of place, like a stump. Monarch butterflies search for somewhere to land, and the speaker thinks of a spot on a map. The mood is calm and quietly wistful. It feels like peace, but it carries a faint sense of loneliness, and the long shadow stretching toward the woods adds to that.
