The brothers have never helped my sister with anything, and they have never given her a cent even if they have money. Now they say that my sister is stingy and selfish, and their words are very dirty.

Why should my family be like that? Just take out some money if you have it. Why do you have to make such a quarrel? Brother and sister are going to do this for the rest of their lives. Just because he doesn’t help you now doesn’t mean he won’t help you in the future. It doesn't mean that you don't need their help in the future, your brother and the others are the same, they are all family members, why do they have to be so ugly when they speak? Also, this is a family matter. As the saying goes, family worries should not be revealed. Such matters should be solved by the family behind closed doors. If you talk about it online, others will not be able to help you. Instead, they will make sarcastic remarks and laugh at you.
