The author Marilyn Fridey said in an interview that during her third year of college, she had become acutely aware of the Women’s Rights Issue.  She had made an attempt to re-examine many of the cultural norms that she had previously accepted as just being "the natural order of things."   One of the paths she had taken to expand her awareness of the female psyche had involved women's literature.  That was why she had spent one weekend of her life in bed--crying, laughing, feeling sometimes confused, and often, incredibly angry and distraught.  On that rainy Friday night, she had decided to read "The Women's Room." She then talked about the book in detail. Myra, the main character whose life was traced throughout the book vaguely wondered why she was not content cooking pot roast, scraping shit from the baby's diapers, and picking up her husband's dry cleaning.  Her only solace was the neighbourhood of women who shared concerns over coffee in the afternoons.
