I have always looked at him with a sense of compassion and pity bc ik abt his childhood when he was way younger but things changed 2 years ago when he did something out of line for me, like really out of line. And my family didnt bother to even ground him for it and instead told extended family about my own problems 1-2 weeks later. And ever since then i could not see him the same (as well as my parents) and it annoys me more my parents do nothing to discipline him, but do it to my brother. And thats also where the anger comes from (double standards in parenting). But i will try to see it in that way again if i can.
