Arrivederci e Grazie (edit 1: Rowens, tomoffing)

[Sequel]

Agreeing with everyone else for the most part, the last two stanzas don't really seem to be a part of the poem. They contrast quite a bit with the first stanza. However, that's not necessarily a bad thing. Hell, almost every Italian and English sonnet ever written include a volta or a turn that shifts the poem into a different direction. The trick is to be able to tie it all together with the last few lines.

I would suggest breaking up the first stanza and using the same bitter words you did in the last couple stanzas, mainly because those are the most memorable parts of the poem. Great job, Poet!
