"Nothing. Only I haven't a dress and so I can't go to this party. Give your invitation to some friend of yours whose wife will equipped better than I shall."

This is an excerpt from the short story "The Necklace" written by Guy de Maupassant and portrays the moment when Mathilde is saddened by her economic condition.

Explanation:

Mathilde is a married woman who lives an economically stable life, but without many luxuries, since her husband's work manages to pay a friendly life, but without wealth. She hates this situation, because she wanted to be a woman of many jewels and extravagant things like her friend, who she dies of envy.

The above excerpt shows the moment when Mathilde's husband gets an invitation to a very important dinner and is excited to take her out for fun, but Mathilde is very disappointed because she doesn't have a new dress to wear, her husband is left with sorry for her and makes an effort so she can buy the dress.
