" Come, come, leave off play, and let us away, Till the morning appears in the skies." "No, no, let us play, for it is yet day, And we cannot go to sleep; Besides, in the sky the little birds fly, And the hills are all covered with sheep." "Well, well, go and play till the light fades away, And then go home to bed." The little ones leaped, and shouted, and laughed, And all the hills echoed. "

― William Blake , Songs of Innocence and of Experience
