Hot cold                                                             ­                         
Light  dark                                                     ­                       
Up down                                                  
Man woman                                              
Love hate                                                             ­       
Solid liquid                    
Sun moon          
Good evil  
Open close
Awake asleep
Never.... soon?
                       All twins everywhere merge with something more,
                       whether a hospital bed, or an airport lounge,
                       Terminal, but a door.  
Life death                                          
   Black white                            
       Day night                                                    
       ­      Right wrong                  
                  Left right       ­
