Sra. Robinson é o original cougar , por assim dizer.
Ela seduz Benjamin simplesmente porque está cansada de seu casamento e quer um divertido encontro sexual. O Sr. Robinson certamente não estava ciente disso.
Do Wiki :
Mr. Robinson, [once he learns about] his wife's affair with Benjamin, goes to his apartment in Berkeley and berates him, threatening to have him prosecuted to the fullest extent of the law, should Benjamin ever come near Elaine again. In the meantime, Benjamin has tried to tell Mr. Robinson that his wife has manipulated him into having an affair with her. But Mr. Robinson is also skeptic and refuses to believe him, and then he forces Elaine to drop out of school and takes her away to marry Carl. She leaves Benjamin a note, saying that although she loves him, her father's anger would prevent the family from ever accepting him as Elaine's husband.
Sr. Robinson ficou indignado quando soube das ações de Benjamin, culpando-o inteiramente por isso.
Rebecca Neumann em um artigo sobre o filme deu uma explicação sobre as ações da Sra. Robinson:
The film places significant emphasis on Mrs. Robinson's past as the motivation for her actions. As a young woman, an unplanned pregnancy forced her to give up her dreams, drop-out of college, and marry Mr. Robinson. Years later, her loveless marriage and empty nest bore and embitter Mrs. Robinson despite her luxurious life-style.
Então, não , a sedução de Benjamin por parte da Sra. Robinson não foi definitivamente um plano para manter ele e Benjamin separados. Acabou acabando parecendo assim, devido à relutância do Sr. Robinson em deixar Benjamin se aproximar de sua família novamente.
