I seek no more to bridge the gulf that lies 
Betwixt our separate ways; 
For vainly my heart prays, 
Hope droops her head and dies; 
I see the sad, tired answer in your eyes. 
 
I did not heed, and yet the stars were clear; 
Dreaming that love could mate 
Lives grown so separate;-- 
But at the best, my dear, 
I see we should not have been very near. 
 
I knew the end before the end was nigh: 
The stars have grown so plain; 
Vainly I sigh, in vain 
For things that come to some, 
But unto you and me will never come.
Ernest Christopher Dowson
