True. But it's kind of sad if you think about it. Brothers and sisters will be there forever until death. Unlike friends or relationships which can be temporary.

From this year on, I am at least trying to get closer to my sister even if we have not been "friends" before.

I have a surprisingly decent relationship with most of y nuclear family with one exception, most of my brothers live hundreds of thousands of miles away from each other.

I’m almost certain at this point that in order to maintain a good relationship with my family distance is required. When my parents moved last, they ended up close to family that they were really close to and far away from family they had feuded with in the past. By the time I visited last year, they relationship with the family they were close to had severely degraded, and all the family they used to fight with were friendly.

you can spend a decade living with someone without any shared struggles. relationships can have the same problem. they love each other, but they never had to actually rely on each other. if that weren't so there would not be any divorces.
