So often concerned with the pettiness of the bourgeoisie, Maupassant has created a character in Mathilde Loisel who has always been selfish and petulant; never is there any mention of her concern for her husband's feelings, for example. Likewise, she accosts Mme. Forestier on the Champs-Elysees and tells her proudly how she replaced the necklace with one that looked similar, having had nothing else but her false pride to sustain her meagre existence.
Imagine, then, her reaction to Mme. Foresier's sympathetic remark, Oh, my poor Mathilde." Do you not think that Mme. Loisel would find this remark condescending and humiliating after she learns that she has worked and sacrificed the best years of her life for an illusion, for nothing? How would she feel? Could she think of telling her husband whose life has been ruined because of hers?
Indeed, the suggestion of Post #4 that she might consider asking for some monetary compensation from Mme Forestier is a good one. Yet, would she bring herself to do this, with such false pride that she has? Certainly, it is a troubled and defeated Mme. Loisel who returns home that Sunday.
