For this exercise, you'll need to come up with a distant memory. It should be somewhat vague but haunting, the kind of visceral memory that has lodged within your mind for no particular reason, but at the same time peters out when you try to recall it: How does it end? What happened then? How did it all turn out? What point of resolution did the memory arrive at? You shouldn't know the answer to any of these questions before you sit down to write this poem. Once you've picked your memory (which most likely is from childhood), write it down in the present tense, as if you're recording it as it's happening this very minute. Concentrate on the concrete details of the scene--smells, sounds, sensations--and don't try to make sense of how the events unfold. There should be no reflection or transformation in the poem--you are not older and wiser and looking back at that experience. Instead, you are once again immersed within it, as befuddled by it now as you were then. When you're done, you should have a poem as unsettling and unresolved as the memory itself.
