No one's a Mystery by Elizabeth Tallent

This story is part of a dialogue between a married man cheating on his wife with a very very young girl. The speakers are always evident, but the problems they both have are slowly revealed. The married man clearly doesn't love his wife anymore since small habits irritate him- small habits that his wife has had probably since the beginning of their marriage. The wife honks back at him, a wordless signal that shows she is oblivious to her husband's displeasure. The married man is also insecure about the future of his relationship with the young girl since he predicts a break-up in the next year or two. He knows he can not leave his wife, and the reader is left with a feeling of sympathy when the girl stubbornly expresses her optimism at eventually being married to him.
