Did I miss something? Did the 13yo mum not say anything about the father? So some unanswered questions there. She said that she was 'experimenting' with sex at a very early age - but made no mention of the father?
imperial, are you saying that you think the father was the man who is actually the adoptive father? That's a can of worms - especially as the mother was only 13.
I agree that the mum and daughter might not bond. The mum seemed very hard - but not surprised, given what she had been through so young and possibly something quite awful for her. The daughter seemed very fragile, emotionally.
I felt so sad for the son too. An unhappy childhood with his birth mother and his disinterested adoptive father. One of his first questions to his birth father "would you please call me 'son'?" Another fragile adoptee.
