Love, We Must Part Now by Philip Arthur Larkin (1922 - 1985)
Love, we must part now: do not let it be Calamitious 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.
