It's about my sibling who is actually going through a bad phase of life. He has always been a very smart person right from his childhood. I was considered a stupid and he the scholar right from his infancy. Even in studies he was always a topper. He always used to go out of his way to help others and even now helps people in need monetarily. Coming back to my brother, though he is younger to me he has acted like my elder brother. He managed my whole wedding and even after my wedding, many issues were sorted, negotiated by him and not my parents. Problem now is my brother feels whatever he does is the right thing. He has a very stressful job and he is always short of time. Few days back, for some major repairs in the house, he didnt consult any of ours opinion. I repeatedly warned him about the contractor that he is charging a lot but he didnt pay any heed to me. He said his work is good so he charges a premium. Just to save his money I had to shout n tell him that the guy is not as good as he thinks so. He called me an idiot n shouted back saying I have objection for everything. It was like a big fight. Now today he somehow realised what I said was correct. He says he is now filled with anger for charging so highly n just feel like giving the contractor a good verbal dose. I told him to let go the money as it was his mistake that he didnt crosscheck. But he is not admitting his mistake. The way he insulted me, I just want to give a good dose to my brother, but I know he is having a bad time. Nobody corrects him, and he thinks he is always correct. His bad time of life, I feel also happened due to his arrogance partly , but I also feel sorry for him. What to do.
