I dunno, I think I love my brother and want the best for him, but I am also really realistic as to the type of person he is.
Him and I are two years apart, with him being older. He was also the only male born in our family in our generation, I.e. all my uncles and aunts had girls. And because we lived in a 3rd world country shithole, everyone was fawning over him because "male heir". He never had any responsibilities, and if asked to do something, he would throw a fit (literally till he was in his 20s, probably still does kek) and would be let go. My grandma, who was extremely abusive towards me, would baby him and compliment him and love on him. And he treated her like crap and never wanted to spend time with her, but she overlooked all of that. One year, for christmas, she gave him a computer and gave me a disposable camera. He would do really bad academically, almost failed out of high school, my parents paid big bucks to send him to a private university cause he "wanted to be a lawyer" and when, in that same year, I was being kicked out of my flat, they told me that I should stay there, even though the landlady was starting to evict me. Because they didnt have money. He is now 32 and his last gf was 19, he has no education and still works service industry jobs, changing employment every couple of weeks. I find it hard to hate him though, as he was always really kind to me and was my best friend when we were growing up. I think i resent my family and my parents for the shishow that out childhood was, and I sometimes feel those negative feelings towards him, but all in all he was just spoiled.
In conclusion, it's great to have siblings, especially if your parents are sound.
