Analysis of A Good Boy

I woke before the morning, I was happy all the day,
I never said an ugly word, but smiled and stuck to play.

And now at last the sun is going down behind the wood,
And I am very happy, for I know that I've been good.

My bed is waiting cool and fresh, with linen smooth and fair,
And I must be off to sleepsin-by, and not forget my prayer.

I know that, till to-morrow I shall see the sun arise,
No ugly dream shall fright my mind, no ugly sight my eyes.

But slumber hold me tightly till I waken in the dawn,
And hear the thrushes singing in the lilacs round the lawn.
