A twenty-year-old man and a twenty-seven-year-old woman are sitting having coffee. She asks if his habit of talking to himself is something he always has done. He does not know what to say. She is married and they are sleeping together. It is an affair. Her husband travels a lot for his work, and has a collection of opera music that the man admires. He never listened to opera music. The wife says she doesn’t quite like it. The wife says, however, that she is happy with her husband and daughter. This puzzles the man. Why then, is she sleeping with him? He wants to ask but doesn’t know how. She is sensitive and cries a lot. He doesn’t do much when she does. When she finishes crying, she usually tries to have sex with the man. He doesn’t want to make her cry more by bringing up the question.  He thinks of other women he has been with and wonders why people are so different from one another. He thinks about the key to unlocking life. He feels people's unique tendencies are more important than age. The two of them had more differences than similarities. After they have sex he knows there is no more he can say to her. He does not feel rejected by this fact, but rather, indifferent.  Their sex is unlike anything he had ever experienced before, it is like a neat room that had strings one could pull to make things happen. He feels he always lives by his values unless he is in this room. He wonders often if he is in love with her but can never answer this question with any conviction.  After they have sex, the woman always looks at a clock. Whenever she looks at a clock, a train always sounds.  He remembers the day she first asks about his talking to himself. They have sex and he does not remember what made her cry. There are sounds of trains and a piano. They both go to get ready. Later, when they share coffee, she asks him about this habit. He does not know what she is talking about and is confused as to why he would not remember his own talking to himself. She says she used to do this but he mother made her stop. They talk about her dead mother and wonder why talking to oneself is so bad.  She says he talks about airplanes and speaks as if he is reciting poetry. He finds this even more puzzling as he does not consciously think of airplanes. He asks her to write down what he says the next time he speaks. She takes a pen and begins to write. As he watches he continues to wonder why they are sleeping together. The moment is intimately silent. She shows him a poem about airplanes that he had uttered while talking to himself. He does not remember doing this. They wonder what the poem about the airplane means. They think about why he is thinking of an airplane in his heart and he wonders who is going on the airplane with him.  They are thinking about the same thing now. She cries, this is the first and last time she cries twice in one day. He touches her hair. He feels like it is real life, hard and smooth and far away. In the future, he thinks to himself that this is a story from a time in his life when he talked to himself as if reciting poetry.
