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 Lee Frost
