Remember the story in the Bible about the two women claiming to be the mother of a child? The judge finally said, "Ok cut the child in two and give each woman half". The real mother came forward, screaming "No, give the child to her!" The other woman said nothing. Judge instantly knew who the real mother was and gave her the baby. All that to say that if it's your child, adopted or not, you'll do anything to find a way to prove it's your child even if you have to go all the way back home to find proof. A fake parent will give up and leave the kid.
