Things that are hard to understand

Love, we must part

Love, we must part now: do not let it be
Calamitous and bitter. In the past
There has been too much moonlight and self-pity:
Let us have done with it: for now at last
Never has sun more boldly paced the sky,
Never were hearts more eager to be free,
To kick down worlds, lash forests; you and I
No longer hold them; we are husks, that see
The grain going forward to a different use.

There is regret. Always, there is regret.
But it is better that our lives unloose,
As two tall ships, wind-mastered, wet with light,
Break from an estuary with their courses set,
And waving part, and waving drop from sight.

Philip Larkin
