Should I put up with my sister-in-law bullying me? Please, great gods.

It is a fact that she is your sister-in-law, whether it is her sister-in-law, her brother-in-law or her sister-in-law. When she entered a house, she had to get along again. People have different tempers. If your sister-in-law is the kind of person who speaks freely, she will only say it and can't let go of things in her heart. If she deliberately provokes trouble and is strong, then your brother has found a strong backing. Whoever marries such a woman will have no peace. Your mother is right. But if it goes too far, your mother doesn't have to be so patient with her. Excessive tolerance will only encourage her arrogance. You have a good relationship with your brother. If it's really your sister-in-law's fault, you can talk to your brother. People should be reasonable in everything they do.
