I have always felt that in this world, except for your parents who can treat you well and give you money without asking for anything in return, everyone else has to settle accounts, especially after you get married.
My father and my uncle are real brothers. They fought over the problem of providing for the aged and the house more than once, but they refused to give in. They just wanted to take the house for themselves and refused to provide for the aged. My dad wants to settle accounts between the two families, and no one will suffer. However, it was rejected by the other party, and the burden of providing for the aged completely fell on the father. The problem of the house has not been solved. My uncle got married last year, but my father didn't go.
In today's society, money can easily lead to contradictions and conflicts. Even if the feelings between friends are no matter how good, once the interests are involved, it is inevitable to be embarrassed. If one party's interests are directly violated, he will have bad feelings, which will affect your relationship.
We live in this world, never think about petty gain and petty gain, and never kidnap anyone with the word "morality", especially brothers whose blood is thicker than water. After all, no one's money comes from the wind, so even our brothers should make clear all kinds of account books and remember to write IOUs when borrowing money.
At the same time, pay attention to proper limit. It's not good to haggle too much, otherwise it will hurt our feelings. There's nothing wrong with putting it mildly.
Therefore, I think that "settling accounts clearly" between brothers is to better safeguard brotherly feelings and reduce conflicts. Between brothers, don't just focus on mutual affection and forget your duty.
