Three random connections from an endless train journey.
He was American; stepped on the train.  Long, lanky hair framing a middle-aged moustache.  Lean and tanned, he wore a carefully pressed grey suit, a grey shirt.  And why the bright orange shoes?  His face was crevassed.  I wished I had the courage to say, 
"Could I take your photograph, Sir.  You look interesting".
The return journey, and I read a book that explains the spread of syphilis in Brooklyn.  It's interesting.  The seat in front of me is occupied by a young Indian lady.  She speaks louder and louder into her mobile telephone.  The language is a curious mixture of English and Indian, and the conversation becomes more heated.  I lean forward and cough discretely.  Later she passes by my seat pushing the drinks trolley.  She apologises for speaking so loudly and I smile.
They will be lovers.  In just a few moments I will hear their hushed, excited, exploratory voices.  I know they will kiss and part endlessly.  They will be lost in it.
This is my train journey.
