This is Mathilda and her husband, and Madam Forestier.
rising action
The necklace is gone!
Ill look for it.
Because Mathilda thinks she desrves to be rich, she is very mean and selfish and stuck up. She is also mad because her husband isn't rich.
Climax
Buy fruit!
Mathilda's husband gets her an invitation to a fancy party but she starts crying because she has nothing to wear, so her husband gives her the money he was saving for a gun to her. She buys the dress and borrows a necklace from her friend, Madam Forstier.
Resolution
I lost your necklace and bought you a new one!
that necklace was a fake!
Some time during or after the party the necklace disapeared and now Mathildas husband is looking for it.
Mathilda and her husband buy Madam Forestier a identical necklace and they spend the next 10 years of their life paying debt off. And mathilda got a job.
Once the debt is paid off, Mathilda comes clean to her friend.
