Si says that he's not sure that he has lung cancer, but he does know that he must live a long and happy life with Roxane. Si tells Roxane that she'll have to live with him for a long, long time. Si wonders if he'll ever be able to understand him. Si says he would never have guessed that he would be like him five years ago, when he first met Roxane, but now he can't understand her. Si asks why there's a heavy jam on the road, and Roxane replies that it's normal for people to have a jam on their way home from work.
