Past perfect—mode of leaving well enough alone,
                as in he had been here but left:
                flat hand of what can’t be undone now—
                not by revision, not by adjustment:
                                doorknob screwed tight,
                                bracket for the cellar step at last;

not like the simple past—thinly strung to the present
                as in he was here but left:
                airborne leaves in updrafts,
                dust caught in scratches on old windows:
                                key in the Honda lock,
                                engine echo in the driveway;
