Some sins have no season. We are as likely to be angry in November as to lose our rag in March ... There is, though, something autumnal about greed, apple-cheeked and wheat-crowned, purpled knee-high in grapes; something summery in sloth, as the hammock creaks in the fly-drowsy heat; and more than a tickle of spring in lust, as birds pair and the sap rises. Among these, ingratitude is winter, the worst of seasons.
