Good-night? Oh, no! The hour is ill
Which severs those it should unite;
Let us remain together still,
Then it will be good night.
How can I call the lone night good,
Though thy sweet wishes wing its flight?
Be it not said, thought, understood —
Then it will be good night.
To hearts which near each other move
From evening close to morning light,
The night is good; because, my love,
They never say good-night.
Percy Bysshe Shelley 1820(?)
