Madame Loisel is common and she wants to be rich.
Madame Loisel's husband received an invitation to a party that is thrown by rich people. Madame Loisel is not happy because she does not have a nice dress to wear to the party and therefore she does not want to go.
Madame Loisel is upset even after buying a brand new and fancy dress because she does not have a jewel or gem to wear with her nice dress.
Madame Loisel and her husband went to the party after Madame Louisel received a diamond necklace from her very good friend and they left around four in the morning.
When the couple got home, Madame Loisel realized that the necklace was missing.
Madame Loisel and her husband have been working hard to pay off the new diamond necklace that they bought for her friend and it turns out that the one they lost was fake.
