What are the motifs in Moderato Cantabile by Marguerite Duras?

Social mores is a recurring idea in the story. Anne is a woman of society, mother of the child, married to an important industrialist. She spends ten years of her life playing the good wife, raising the child, keeping the house, and entertaining her husband's guests and workers. Her life becomes an inescapable daily routine of boredom, devoid of essential meaning. She lives in a big, expensive house in the affluent part of town and directs her servants, prepares many dinner parties where she drinks wine and speaks to various men, and dresses elegantly. She lives without excitement, without desire, and she is judged accordingly as a successful member of the community, someone to be respected and emulated.
