What is the most unreliable thing that the most wonderful mother-in-law has ever done?

I haven't seen it with my own eyes, but I heard from my sister that she has a good friend. Her mother-in-law is very good. She once did a very unreliable thing, which made his friend very angry. I also know her friends. She often comes to our house to play, and she is a very cheerful sister.

That sister already has two children, one is over five years old and has gone to school, and the other is only six months and less than a week. Once, she wanted to go out and wash clothes. In our country, she went to the river to wash clothes, so she asked her mother-in-law to help look after the children. When she left, she specifically said that the child had to pee to remind her mother-in-law to pee. As a result, the mother-in-law only watched TV and let the children pee their pants. Because it is winter, it is difficult for children to take off their cotton trousers. I didn't change my child's cotton trousers, but I just picked up the child and baked it on the honeycomb briquette stove. Have you ever seen such a retarded person? How dangerous is it? The child couldn't speak, and soon he burst into tears. The mother-in-law turned it over and saw that the child's ass was burned red. It's too painful. It pains me to think of it. The mother-in-law took the child to see a doctor and took some medicine.

Later, my sister came back to see the child's ass burning red and cried for a long time. From then on, she never dared to ask her mother-in-law to help look after the children, because the pain was in the child and in the mother's heart. How can a mother not feel distressed when she sees her child suffering? Besides, the child is so young that he will suffer such a crime. The mother's heart will certainly be particularly uncomfortable, preferring to suffer for her children.

This is the best mother-in-law I have ever seen. She can do such an unreliable thing. No wonder her daughter-in-law won't let her look after the children. No one will be at ease!
