Now close the windows and hush all the fields: 
If the trees must, let them silently toss; 
No bird is singing now, and if there is, 
Be it my loss. 
 
It will be long ere the marshes resume, 
I will be long ere the earliest bird: 
So close the windows and not hear the wind, 
But see all wind-stirred.
Robert Frost
