So if poems were people...
...we'd be talking about body language, demeanor, accent, tone, and how these extras affirm/undermine the authenticity of whatever words are coming out of mouths. Inability to meet your eyes means lying or otherwise false. Repressed smirk means a game of some kind; are we gonna play it. Eyelash batting might be cute but is there anything behind it.
I've been thinking about how shocked I feel when I get that somebody who's hating on something I've enjoyed isn't reading "for tone." That's like ignoring the look on the poem's face.
