The speaker has just said goodbye to someone, and the poem never says how it feels. Instead, it shows us what the speaker notices. First come the leftovers: half a hummingbird nest and a broken crock, both things that were once whole or useful and now are partial, damaged, or abandoned. They seem to echo the emptiness the title names.
Then the scene shifts outward. The sun comes out, and a fly circles a crocus, a small sign of spring and ordinary life carrying on. The kestrel in the last stanza keeps returning to the same electric line, and the repetition suggests habit, patience, or perhaps the speaker's own mind circling back to the person who is gone.
The mood is quiet, watchful, and a little sad, but not dramatic. Grief is implied through attention to small things. The speaker is alone, noticing the world with unusual sharpness, and the poem leaves the feeling unspoken.
