32. Reluctance
 
OUT through the fields and the woods   
  And over the walls I have wended;   
I have climbed the hills of view   
  And looked at the world, and descended;   
I have come by the highway home,
  And lo, it is ended.   
 
The leaves are all dead on the ground,   
  Save those that the oak is keeping   
To ravel them one by one   
  And let them go scraping and creeping
Out over the crusted snow,   
  When others are sleeping.   
 
And the dead leaves lie huddled and still,   
  No longer blown hither and thither;   
The last lone aster is gone;
  The flowers of the witch-hazel wither;   
The heart is still aching to seek,   
  But the feet question ‘Whither?’   
 
Ah, when to the heart of man   
  Was it ever less than a treason
To go with the drift of things,   
  To yield with a grace to reason,   
And bow and accept the end   
  Of a love or a season?
