A woman and her lover climb a mountain in the last snow of spring, and he asks once again for marriage. He wants a home, children, a quiet place to return to after a noisy workday. She refuses, saying she has too much to do and see before settling down. But the poem lets us in on what she keeps back: she was never sure of him, and she has heard about another girl and a wife he left behind in Philadelphia. She chooses silence over accusation, calling it "safer," and takes the blame herself.
The mood is quiet, tired, and quietly sad. The speaker sounds calm, even practical, yet the details hint at hurt. The melting snow and soft, damp ground suggest an ending, but also a thaw and a new season. The last lines undercut her confidence: "I know this will be for the best" is something she is "telling my friends," which suggests she is still trying to convince herself.
