Metaphors get under your skin by ghosting right past the logical mind.
At some unnoticed moment, I began to understand that a life is written in indelible ink. What I've chosen, what's happened unchosen, can't be unmade or redone. Poetry, though, is a door that only continues to open. Even the unchangeable past changes inside a poem. Not the facts, but the feeling, the comprehension.
At another level, though, poems can craft an eraser - we can't revise the past, but poems allow us some malleability, an increased freedom of response, comprehension, feeling. Choice, what choices are possible for any given person, is another theme that's run through my work from the start.
