And Dave, in "The Iron Man" (1974), answers Kim's question of marital infidelity with a question of his own that if another woman takes undue interest in him, then what is she doing about it? Kay weaves this complexity into the couple's relationship to counter the paranoia she finds in women of jumping to suspect their partners of infidelity. In an opposite situation when Brad in "Opportune Marriage" (1969) suspects Lisa of infidelity, he confronts her directly but his emotions go flat when he asks whether she is in love. This is in keeping with another assertion made in "Full Circle" (1978) that vast majority of women cannot commit to a sexual relationship without some emotional attachment. In "Full Circle" (1978), the couple's marriage falls apart when Steve is unable to tolerate Sara's infidelity on the basis that sex aside, she must have been emotionally attached to the other man. Lisa in "Opportune Marriage" (1969) acknowledges that she was emotionally unfaithful to her husband if not sexually. She went to this other man for friendship that meant gentleness, tenderness and kindness, which for her construed an emotional cocoon. As Brad in Opportune Marriage (1969) says for everything that he was not. While Brad realizes what was lacking in him, Sara convinces Steve in "Full Circle" (1978) that her past indiscretion was an attempt at stark revenge for which she had no emotional attachment and that she reserved her deep love for him only. Having established a marital relationship on the basis of sexual compatibility and fidelity, the couple's personal knowledge of each other's virtues and vices come only with time. Soon after their marriage In "Dangerous Moonlight" (1985), Andreas asks Lyn that she doesn't really know him, does she? Although she is mortified by this discovery, he is unperturbed. Lyn finally realizes that she has all the years ahead of her to find out the answer to his query. To Sara's assertion in "Full Circle" (1978) that men are at their most vulnerable in the aftermath of sexual intercourse, a more experienced Ailsa tells her that men even then know what make them tick. It is In "No Passing Fancy" (1980) that a father advises his daughter, who demands more alone-time with her husband, saying that a man's career is his pride, and so not to get him away from it. A failure in career constitutes actual vulnerability in men. In "Full Circle" (1978), we learn that when a man is sick, depressed, or faces a setback in his career, is also when the woman can penetrate into his ego.
