Guys, I simply cannot contain my shock and anger at what an actual, truly and for real ASSHOLE this dude is. He is grown, and has literally spent the last 16 years ignoring, mistreating, and otherwise disregarding his own sister because she was adopted when he was a small child and his spoiled 8-year-old ass didn't want that. Not enough? How about that he still firmly believes that his parents have mentally abused him for those 16 years because they went ahead and adopted the girl even after he said no and then let her stay and be raised as part of the family. STILL not enough? Let's not forget the very premise of his question, which is that he has a brother the exact same age as the sister, whom he has none of these issues with and treats properly as a sibling. Right in front of her. Like she's a fucking ghost in the room. So either the issue is that she's not "real" family, or, (more likely in my personal opinion) that's she's a girl. Yeah. Bust out the popcorn for this one.
