Answer: It took Loisels a decade to pay back the money they borrowed to buy the necklace. And, it changed everything for them. They had to move to the poorest quarters of the city.
With no maids or assistance, Matilda had to cook, clean, mend, sew, bargain with the grocer and butcher to save every sou ( a french coin of low value) just for mere survival. The husband had to work in the evening and night to pay the debt.
In this way, the course of the Loisel’s life changed due to the necklace.
