You and your gorgeous use of extended metaphor, one as powerful as the sea. Just when I think you can not take what you have so beautifully woven any further, the tapestry has more details added, more appeals to the emotions and senses:

only an indecipherable message is delivered
upon the fickle breath
of a mercurial
absent-minded zephyr

All gorgeous, white spray cresting waves. and if your imagery and extended metaphors had not yet pulled your readers under these waves of longing, than your appeals to the senses would be the siren's calls that would, I fear, do them in (as they have me).

Lovely poem and read, @prydefoltz, thank you for sharing.
