GOOD-NIGHT. Good-night. Ah, good the night
That wraps thee in its silver light.
Good-night. No night is good for me
That does not hold a thought of thee.
Good-night.

Good-night. Be every night as sweet
As that which made our love complete,
Tilt that last night when death shall be
One brief 'Good-night,' for thee and me.
Good-night.

Silas Weir Mitchell
