Plot
On a winter morning in an affluent suburb, the Woman – having just said goodbye to her stockbroker husband and their two young children – is going to London, shopping. She drives to the station which is shown as Cobham (referencing Cobham, Surrey or Cobham, Kent). Among the crowd, as she boards the train is the Boy. It is his birthday today and he's determined to make the day a different one.
The Boy moves up and down the crowded corridors. The Woman in her non-smoking compartment badly wants a cigarette and starts to scrape away a 'No Smoking' sign. The Boy is attracted by this middle class rebellion, pulls the sign off and presents it to her and tries to engage her in conversation.
Later, battling her way into a department store she finds he has followed her. Leaving the store, she thinks she has lost him. But he catches up with her on a crowded pavement. She tries to throw him off, he finds her again. She flees to her mother's apartment – followed by the Boy. The Woman is desperately embarrassed and tries to explain, but her mother treats the whole thing lightly and the Woman learns with surprise that her parents both had affairs with other people during the war. Mother says 'He's good for you. If you have an affair with that boy you'll regret it. On the other hand, if you don't have an affair with him you'll also regret it...' He tells an estate agent that he is a successful talent agent and gets the keys to an empty flat. The Woman and the Boy have sex together there. He tells her that he loves her and suggests they have an affair, but she declines his offer. She goes to London Victoria station and goes home.
