"La noche buena se viene,
La noche buena se va,
Y nosotros nos iremos
Y no volveremos mas."
-- Old Villancico.

Sweet evenings come and go, love,
They came and went of yore:
This evening of our life, love,
Shall go and come no more.

When we have passed away, love,
All things will keep their name;
But yet no life on earth, love,
With ours will be the same.

The daisies will be there, love,
The stars in heaven will shine:
I shall not feel thy wish, love,
Nor thou my hand in thine.

A better time will come, love,
And better souls be born:
I would not be the best, love,
To leave thee now forlorn.

Mary Anne Evans
