You talk; some hear, some don’t.  They have heard the words, 
                         but not taken them in.  There is no response. You shout. 
              They turn around and ask: ‘What do you mean?  You know they’ve  
               heard you. You repeat the utterance so they do not misunderstand.
                                 		          Later   you   start
                                            	         to  talk again, but 
                                  	                 the  people   who 
                                  	                listen rarely reply,
                                   	                you  start walking
                                  	                around,   flipping
                                                       a hand up in the air
                                                      as if you had nought
                                                     to say,  finally there is
                                                    need for less shouting 
                                                    instead, you stammer
                                                    'Just talking to myself ’
                                                 shrugging  your  shoulder
                                          and flipping your hand in the air.
