The poem begins with a question that sounds a little lost: has the world always been this dark, or is the speaker the one who has changed? The sun might be resting, or it might have burned out for good. That uncertainty gives the opening a quiet sadness. The second stanza stays in the same muted place. Nothing is freezing, but nothing is really warm either, so even a light wind barely registers.
Then the tone shifts. The speaker turns to another person and says they like their "dimmed light." Instead of longing for the sun, the speaker finds comfort in something soft and low. It becomes a private, safe place that nobody else knows about. The final stanza says this love doesn't have to be "loud and proud." All that matters is "you and me." The mood is gentle and intimate, and the closing line suggests that the darkness has become a shelter rather than something to escape.
