Do I dare	        
Disturb the universe?	
In a minute there is time	
For decisions and revisions which a minute will reverse.	
 For I have known them all already, known them all:	
Have known the evenings, mornings, afternoons,	        
I have measured out my life with coffee spoons;	
I know the voices dying with a dying fall	
Beneath the music from a farther room.	
  So how should I presume?
