Tbh it sounds like OP was trying to troll after the comments started turning against the daughter, but even if he IS picking on her, it wouldn’t be her fault but could it have anything to do with the fact the man who raised him abandoned him for her? Like both parents are massive AHs even if the son sucks too, but I’m talking about the grown man who raised a child for a decade and not only abandoned him, but stayed in his life just enough so he could see through his sister the only father he’s ever known, choose not to care about him at all. No matter how the children are behaving as a result, it’s the parents who have handled raising these kids horribly and if they were real it make me feel sad for the kids.
