What should be the relationship between brothers?

"Brothers", so-called brothers, brothers, are all children of a mother, and naturally they are closer than others. Whatever happens, they can handle it. There should be no big contradiction between brothers, which will make others laugh.

"Brothers are fighting, father and son are fighting", which means that there is no generation gap between brothers and they are best friends. So I tell you, whether brothers or brothers, everything should be kind to each other. It's called brother.
