Another way Madam Loisel changed in The Necklace, is how she had to stop relying on her husband to make a living. This started as she had to start working off the debts that the loss of her necklace resulted in. This changed her and her husband's relationship and gave her more of an appreciation for him. This changed her for the better.
Throughout his story, Wright also gained a new sense of responsibility and independence with his mother off at work all day. This left him to take care of him and his brother, dress himself, and also prepare food for the two of them. I believe these actions changed Wright for the better.
Madam Loisel also changed again in the middle of her story. This happened by her going to the ball and experiencing the life she believes she was meant for her whole life. This let her finally know what she felt she was missing out for, and in the end made her more grateful for all she had. This changed her for the better.
