Two short scenes sit side by side here. In the first, the sun is going down and ravens are calling. The speaker treats their harsh, croaking voices as "a most admirable music," a phrase that sounds a little formal and a little amused. It suggests someone who has learned to find beauty in things others might call rough or gloomy.
The second stanza turns to "we," a pair who "fell into rare life and then to bed." The word "fell" makes it feel unplanned, as if joy and desire simply caught them. "Rare life" suggests something precious and uncommon, and the title, "Late bloomers," hints that it arrives later than expected, though the poem never says how old they are.
The mood is warm, quiet, and slightly wry. Evening is a time of endings, yet the poem treats it as a beginning. The speaker seems content, even grateful, and the plain final phrase "to bed" keeps the moment human and unshowy.
