“To sleep! to sleep! The long bright day is done,
And darkness rises from the fallen sun.
To sleep! to sleep!
Whate’er thy joys, they vanish with the day;
Whate’er thy griefs, in sleep they fade away.
To sleep! to sleep!
Sleep, mournful heart, and let the past be past!
Sleep, happy soul! all life will sleep at last.
To sleep! to sleep!”
Alfred Tennyson
