Bonta's short poem begins with a bold idea: any change at all counts as news. The example he gives is tiny, "a quiet stir to the oak," the kind of movement you'd only notice if you were paying close attention. Big headlines aren't the point. News here means the slow, subtle shifts in the living world.
The second half turns to the poet, and the tone gets a little playful. The poet is described as "if not conceited," a hesitant, almost joking qualification, as if the speaker isn't sure it's fair to claim much for poets. Then comes the surprising comparison: she is "particular as water in her loves." Water takes the shape of whatever holds it and finds its own path, so the line suggests a person whose affections are exact and specific, yet fluid. The mood is calm, observant, and a bit wry. The poem seems to say that attention to small things is what a poet does, and that it's a form of love.
