How should brother and sister get along?

Just like my two aunts, they get along well face to face.

But secretly telling each other that it's not good, I really don't understand ~

Fortunately, they are not together now ... only once every few years.

I don't have this problem myself. My husband has only one sister.

And we're not in the same city.

But then again, I think everyone is a woman,

In fact, we should be honest with each other like sisters and get along well.

After all, they are married to this big family! They are all family.
