Answer:
Mathilde is motivated to borrow things she can't afford in order to fit in with a higher social class.
Step-by-step explanation:
Guy de Maupassant's short story "The Necklace," tells the story of Mathilde Loisel and her desire to be 'equal' to the women of the higher class. And in her greed, she led her family through misfortunes which ended downgrading them further.
The setting of the story is a high society where parties are organized, dinners and balls are a regular occurrence for entertainment and socializing. And in this desire to be a part of the higher class and their "parties", Mathilde spent her husband's savings to get a new dress for the ball. Not only that, but she also borrowed a necklace from Forestier which she ended losing at the night of the ball.
To repay the lost necklace, they gave up her inherited money and also borrowed the rest and bought a new necklace. It was after a decade of 'suffering' that they only learned the truth about the necklace- it was a fake and they had replaced it with a genuine one.
Mathilde's dreams and desires make her borrow things she can't afford just so she can fit in with the people of the higher class.
