I woke before the morning, I was happy all the day, <br />I never said an ugly word, but smiled and stuck to play. <br /> <br />And now at last the sun is going down behind the wood, <br />And I am very happy, for I know that I've been good. <br /> <br />My bed is waiting cool and fresh, with linen smooth and fair, <br />And I must be off to sleepsin-by, and not forget my prayer. <br /> <br />I know that, till to-morrow I shall see the sun arise, <br />No ugly dream shall fright my mind, no ugly sight my eyes. <br /> <br />But slumber hold me tightly till I waken in the dawn, <br />And hear the thrushes singing in the lilacs round the lawn.<br /><br />Robert Louis Stevenson<br /><br />http://www.poemhunter.com/poem/a-good-boy/
