Your brother-in-law's loan business is not smooth, and he owes a lot of debts when he fails to start a business. Then your sister must be having a hard time in this respect. She had expected your brother-in-law to start a business and spend the money he earned, but now her hopes are dashed. She didn't spend the money she earned from starting a business, and she didn't pay off her debts. Her life savings were not enough, so she had to swipe her credit card. Your sister may be a little disappointed in your brother-in-law, but after all, I hope your brother-in-law can make money and pay off the debts he owes. Credit card spending is also temporary. I hope your sister can spend the money your brother-in-law earned when he makes a comeback. Good luck with everything.
