Bruce Grove to Liverpool Street

A young couple sit on the train going to work.  He looks boyish with a man's haircut, tired eyes and a smattering of facial hair. She is serene and quietly pretty. Like side characters in a costume drama, playing maids and kitchen boy from downstairs. They are not speaking to each other but occassionally she turns from looking out of the window and smiles at him. It causes him to smile back and his face brightens. Neither of them read, paper or book. He is listening to one headphone.
