Do all precious mothers have little sisters-in-law in their husbands' houses? How's the relationship? What will you do if you meet an unreasonable sister-in-law? Tell me about me first.

Very disobedient, swearing, and playing with people. I haven't communicated much with her. My mother came to say hello to her and ignored anyone. She also closed the door. Her son is brought by my mother-in-law, and we have never been separated from her mother-in-law. We often buy food to supplement our family. His sister-in-law and brother are both at work, and we didn't pay a cent for meals in the first half of the year. Her son has been here for six months. My baby fell asleep many times and was awakened by her loud voice. It pains me to see it. I went out to say hello to her and said to keep my voice down. On the contrary, she is louder. She stood under our window, explaining something to her mother-in-law. Because my husband greeted her twice before going to work, and she ignored me, I got angry and went out to scold her. Because people don't do this at this time, I argued with her. Later, I went to see me. What, when she saw the biscuit, she said, this is Oreo. I was so angry that I didn't speak. Later, when she saw that my husband and in-laws were away, she asked her son, why are your ears so red? I was there alone, clearly saying that I hit her son. That tone makes me angry. Later, my mother-in-law came, and I said, Grandma, did you pinch his ear? His mother said his ears were red, and her mother-in-law said he didn't. He made it himself. I was very angry. Too many. She used to eat at her home. It is estimated that this time her mother taught her to let her mother-in-law bring her food. I really don't want to see her. I am very angry. Ladies, what do you think I should do? How to get along with people like her?
