The poem begins with a wry confession: so much poetry is about poetry, and the people who read it are mostly other poets or those in mourning, searching for words to fit a funeral. The speaker suggests we turn to poems for sound and feeling rather than clear answers, and that we're content with hints.
Then the poem moves outdoors. After nineteen days of cold, bright weather, the city goes back to being rainy, and the speaker describes it with obvious affection: streaked windows, the smell of wet soil, cars swishing through puddles. People get ready for "mysteries" by knitting bright pink hats and scribbling slogans on cardboard, which hints at some kind of protest or gathering.
The mood is quiet, wry, and a little somber. The title suggests the speaker is at ease with rain, and the ending links that ease to uncertainty. Nobody can know what the weather will bring until it arrives, and the blunt image of the "corpse" brings back the poem's thread of grief and loss.
