Mathilde met Jeanne in the park. But Jeanne didn't recognize her at first. Later she knew it was all because of the necklace Mathilde borrowed from her 10 years ago. It was lost on their way home. The Mathildes had to borrow thirty-six thousand francs, buy a diamond necklace exactly like the one they had lost and returned to Jeanne.

To pay for the money, they worked night and day. They had little food and never had a moment to rest. At the end of ten hard years, they had paid off their debts. Mathilde looked so old that Jeanne didn't know her when she met her in a park one day.

When Jeanne learned Mathilde's story, she told her that the necklace she lent her was not a real diamond one. It had cost her only five hundred francs.
