Dave Bonta's short poem opens with a strange inner weather: "a little winter and summer rise within." The speaker feels two opposite seasons at once, cold and heat, perhaps hardness and warmth, stirring inside the same body. It's an unsettled, divided state.
From there the speaker admits to being "in the business of anger," and says they might "say anything severe." That phrase sounds half like a warning and half like a confession: the speaker knows harsh words are close at hand and doesn't promise to hold them back.
The last lines cast the speaker in two roles, "a simple rogue" and "a troubled king," both of whom "sing of the plots against peace." The images are playful but uneasy. A rogue is a small troublemaker, a king is a ruler, yet both end up singing rather than fighting. The mood is tense and restless, with a dark humor running underneath. Anger is on the surface, but the song suggests the speaker is turning that turmoil into something spoken, even performed.
