Lets just keep it a thou-wow. What happens to the kid when it becomes a young adult is of no concern to her. That kid will most likely grow up emotionally neglected as she has already said that when her mom was ill she had no room for anyone in her life. What happens when she gets ill? Will the kid have emotional support? Of course not. All we can do is hope there's a family therapist.Because her behavior spits in the face of nature and is harmful for the species.
That child will be a young teen when their mom is old and dilapidated. Surely leaving them stuck caring for their ancient parent.
