Wrath!

Hm, very reminiscent of the poem about... well, off the top of my head, I don't remember the poet's name or the particulars of it, but about someone leaving a note apologizing for eating some fruit. Nice inversion of it as well. It doesn't hang together as a plot so much (that last line would imply the narrator had made some agreement to eat the grapes, which doesn't make sense). It even feels like it's an amalgam of that poem and the fable of the fox and the grapes. Taking that into account, it reads less like the poem it's based on, which does improve things. Then I don't take this as a note to the owner of the grapes, more like the narrator's internal musing of how he might speak to such a person, and in this context, he might even be only imagining it as a hypothetical person. Nice wry humor in this.

Evaded the snooty snarl of millions
While his verse made quiet bother toward
His dear native Rutherford.
