Mme Forestier proved to be a true friend of the Loisels. When Mme Loisel had no one, it was Mme Forestier who helped her. She let her try all her jewels and asked her to borrow whichever she liked the most. Matilda tried each and every piece of jewel and lastly found a superb necklace of diamonds packed in a black satin box. Mme Forestier agreed to let Matilda borrow that without hesitating even once. Later, in the end, when Matilda tells Mme Forestier how much trouble she had to go through because of the diamond necklace, Mme Forestier felt very sorry and told her the truth that the necklace was fake. She could have said that the necklace was real but she chose to tell her a truth. All these things show that she was a really nice person.
