I have 2 ideas about it: 1- It is stressful cause we are too involved. Try to look at the situation as an observer. What would you say to me if I have asked you the same thing?
It may help you to think without emotion and calm down. 2 - Maybe you spend more time together than you should. For example, when my sister got married the rivalry died.
Why? Now we have no time to discuss! When she comes home we start by telling the good news and before there's time for more she and my brother-in-law got go.Simple.
Hope you be OK!
I think sibling rivalry never dies, because one way, the other parents, or other family members contribute to it. I also believe that sibling rivalry is worst between sisters. I would recommend that you try to be the adult one or the mature one.
But also look after yourself.
There's a term called enmeshment when people are basically too involved in each other's business-boundaries are not respected. Then, there's the matter of parent's contributing to sibling rivalry. Siblings are going to have disagreements but when parents show favortism it only makes matters worse and this is unfortunately passed down from generation to generation.
I think families would experience less conflict if people would learn to mind their own business and learn how to treat one another.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
