A very rich merchant of St Denis had a beautiful wife and a splendid household. His wife liked to buy fancy clothes and organize parties, one of their favorite guest was a monk.
One day the monk paid a visit to their house, the wife was alone complaining that her husband wouldn't give her one hundred franks to buy a dress. The monk was very interested in helping her out and the lady could see it. Therefore she told him that she would show her gratitude if he could give her that amount. Then the monk promised to give her the money.
I need my money back !
You only need to ask your wife
Few days later before the departure of the merchant the monk asked him for a loan of 100 franks and the merchants gladly accepted to help his good friend.
WHAT HAPPENED TO MY MONEY !!!
After the departure of the merchant the monk came to the wife and she accepted to spend the night with him in exchange of the 100 franks.
Sometimes later the merchants stoped at the monk's abbey to pay a visit and to get back his money but the monk told him that he repaid his wife only few days after he had borrowed it.
When the merchants came home he asked his wife for the money and she confessed that she spent it all in clothes and the promised to repaid him in bed. The merchant accepted her excuses and asked her to stop being so extravagant.
