(quote)

Good-night? ah! 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.

- Good-Night
poem by Percy Bysshe Shelley
