I agree to reveal a secret in a sonnet, Inez, my beautiful enemy; but no matter how well I set it up, it cannot be in the first quatrain.
Here, come to the second: I promise you that the secret won't slip without my telling you; but I'll be ******, Inez, if eight lines of this sonnet haven't already gone.
See, Inez, how hard life is! With the sonnet already in my mouth and every last detail planned,
I counted each line and have found that according to the rules by which a sonnet plays, this sonnet, Inez, is already finished.
