Frank Bernhard criticizes the metaphors Shakespeare uses to describe the passage of time, be it the coming of death or simply the loss of youth. Though lyrical, they are logically off and quite cliché, being the overused themes of seasonal change, sunset, and burn. In fact, the only notably original line is the one concerning leaves, stating that "when yellow leaves, or none, or few do hang, upon those boughs". Logic would require that few should preceed none; in fact, if the boughs were bare, no leaves would hang.
