My brother wants to give me 654.38+ 10,000 yuan to do business. What if my sister-in-law doesn't agree?

In this case, you can't insist, and you can't let your brother and sister-in-law quarrel and affect your brother's family. Try to take a step back, tell your brother that the money is borrowed, make an iou, and you will take a step back, which shows that your brother is more accommodating in front of your sister-in-law. Better bring an elder. At first, she said no, now she saysno. If she still says no, I won't pull him/her. Who will pull him/her? We are all milk compatriots. Since he/she said it was borrowed, you can't go too far. I believe your sister-in-law's face will hang up at this time, and with her elders around, she won't have any radical words.

If this doesn't work, there are only two possibilities. First, my brother and sister-in-law are playing black and white, but they just don't want to borrow it. Second, your brother can't afford to be a family at all, so you don't want it. Sell it well.
