How is Madame Loisel greedy?

In “The Necklace” by Guy de Maupassant, it is stated that Madame Loisel “suffered endlessly, feeling herself born for every delicacy and luxury." Even though she comes from a poor family, and is married to a simple clerk who works at the Ministry of Education, she dreams of classy things and is envious of those people who possess these things. For instance, she is greatly disturbed by the possessions of one of her rich friends, whom she refuses to visit on this basis. She is discontented by what she has and is always keen on acquiring what she cannot afford to have. Thus, when her husband, in trying to please her, gets her an invitation to a party at the Ministry of Education, all she can think of is the dress she is to wear at the party. She does not even consider how difficult it must have been for her husband to get them invited to the party. Her actions show that she is a greedy person who is full of herself.
Another example of Madame Loisel’s greed is her inability to choose a simple piece of jewelry from the pieces offered to her by her friend, Madame Forestier. In spite of being shown many pieces, she still asks whether there are more pieces to be seen. The necklace she finally settles on is quite beautiful and when she wears it to the party, makes her the center of all attention. However, she loses this necklace on her way home from the party. She and her husband then have to replace the lost necklace at a cost of about thirty-six thousand francs. Her greed and vanity, therefore, pushes her family into great debt.
