Mathilde is vain, and it can be seen from her dream that she has a beautiful and luxurious house with exquisite furnishings. She envied others for beautiful clothes and jewels, and she envied others for having groups of servants, which laid the foundation for her later borrowing necklaces.

But from her ten years of hard work, we can also see that she has enough courage to accept them, and she paid the price for her vanity, even though the necklace is fake.
