Three (and a half) Things Poets Should Never Write About

(1) The moon
A lot of poets are insomniacs, or up late drinking, or busy sobbing into their green tea as they draft encomium after encomium about the autumn leaves’ brave last bursts of color against winter and impending death. In any event, we’re often awake at night, and unless you’re in some horribly cloudy place like London or Seattle or something, there’s a pretty good chance of seeing the moon on a given night.

As junior editor/assistant flunky of a literary zine, I fully concur. Though I've seen a lot more self-references to poetry than moon metaphors.
