What is allowed, what is disavowed, what is acknowledged, what is refuted. Don't let the words overwhelm you. Remember that poems are written by real people. Of course we laugh. And, as a poet, you have to laugh twice.
Reality is always an issue.
Reality is but one set of monkey bars in the poet's playground. Take this poem. Once, just once, we kissed so fierce our teeth scraped, our gums bled. We greedily sucked up the salt. Suddenly I was a cannibal, ravenous, tapestried with spears, the vanity of war paint, stalking you the prey, the meal, as you moved through the sawgrass unaware.
