Mathilde was given the opportunity to go out and have fun. But she had to be greedy and she didn't appreciate what she has got.
I haven't a thing to wear.How could i go?
Why,my dear i thought you would be glad.You never go out and this is such a fine oppurtunity
M and Mme. Loisel
Mathilde got her dress but she was still being greedy and wanted a jewel.To get what she wants she was ready to not go to the event at all,
What is the matter?
I hate not having a single jewel, not one stone,to wear.I shall look so dowdy.I would almost rather not go at all.
Mathilde was acting even more greedy and she wanted to use an expensive carriage and she wasn't even listening to her husbands suggestions.
wait a minute you'll catch a cold outside.I will call a cab
Because of her own greedy ways she now has lost the "expensive" necklace that her friend gave her and now she has no one to blame other than herself
what did you say?what?Impossible
The-The necklace its gone
Then due to all the expenses that Mathilde and her husband had to pay back,she did all the work by herself and she finally learned how it would be to work for what you want.
*cries in selfishness*
As she was talking to her old friend,Madame Forestier she explained everything that happened with the effects of losing the necklace. But she was going back to her selfish ways when she was putting all the blame for her downfall on her friend
