If your sister&;s work at home is too busy, you can help her as much as you can. If your sister is in trouble at home, you should lend her a helping hand to tide her over. Because your sister doesn&;t want to do housework, she doesn&;t want to be locked up by housework, and she is angry and complaining. This is your sister&;s attitude towards life from optimism to stage to a nagging dissatisfied wife. If she doesn&;t realize it and doesn&;t want to change, you can&;t change her. Yelling at her two children is one of her ways to educate them. As a younger sister, you have no right to interfere. She lost her temper with the two children for no reason. That&;s just the children&;s story, so don&;t take it seriously. There must be something wrong with the child, and he can&;t satisfy his mother. If he can&;t convince him with a pleasant countenance, he will certainly make a hullabaloo about. Losing your temper on a child can only be said to be childish. Your sister is not mentally . How can she lose her temper with a child for no reason? There must be a reason. A child&;s academic performance can only represent his excellent academic performance, but it can&;t prove that he is an obedient child at home. If your sister tells the child, it must be that your sister has more truths and the child has more lies. Don&;t take her children to your home. It is your sister&;s responsibility to raise and educate them. You have no obligation to raise and educate them for her, and you are not qualified to break up their mother and son. Your behavior is not helping your sister, but breaking up a complete family. What you should do is: &”;tell your nephew that he must listen to his mother, try not to make her angry, and try to share some housework for his mother at ordinary times, otherwise, when his mother is exhausted, your hard life will begin from now on.&”; It is your happiness to make your mother happy. &”; Take the initiative to find your brother-in-law, talk about your sister face to face, let your brother-in-law try to come up with a set of solving strategies, solve the current problems as soon as possible, nip the hidden dangers in the bud, and don&;t wait until the fire is burning. You try to spend more time with your children, give them some questions to answer, make it easier, wake up their sleeping brains, and chat with them more. I believe your efforts will have good results. Only by making yourself stronger and more powerful can you have the energy to help your relatives and friends around you. On the contrary, if the fire at home has not been put out, how can you be busy enough to save the fire at other people&;s homes?
