Good-night? ah! no; the hour is ill <br />Which severs those it should unite; <br />Let us remain together still, <br />Then it will be good night. <br /> <br />How can I call the lone night good, <br />Though thy sweet wishes wing its flight? <br />Be it not said, thought, understood -- <br />Then it will be -- good night. <br /> <br />To hearts which near each other move <br />From evening close to morning light, <br />The night is good; because, my love, <br />They never say good-night.<br /><br />Percy Bysshe Shelley<br /><br />http://www.poemhunter.com/poem/good-night/
