21. A Good Boy
I
I never said an ugly word, but smiled and stuck to play.
And I am very happy, for I know that I’ve been good.
And I must off to sleepsin-by, and not forget my prayer.
No ugly dream shall fright my mind, no ugly sight my eyes.
And hear the thrushes singing in the lilacs round the lawn.
