Mathilde Loisel, the protagonist of Guy de Maupassant's "The Necklace," is unhappy with her life as a whole. Although "pretty and charming," Mathilde finds that life has placed her in no position to obtain the type of lifestyle she dreams of: one of richness and luxury.
Mathilde's "mean walls, worn chairs, and ugly curtains" make her unhappy. She desires a life filled with "silent antechambers, heavy with Oriental tapestries lit by torches in lofty bronze sockets." Unlike other women of her caste (social status), Mathilde did not accept what life had handed her. She wanted more, and her miserable and poor surrounding only reminded her of what she was not born to possess.
Essentially, Mathilde's home serves as a reminder of the position she is in: married to "little clerk" and unhappy because she felt she was living a life "beneath her."
