Oh wow Deanna, that was a cool article.
I never knew my birth father - he ran off right after my mom became pregnant with me. So, I had a stepfather in my life, and I did consider him my dad.
But, it would have been nice to know my real father too, because as a child, I believed his reasons for running off were all about me - in reality, the reasons were probably more about debilitating fear.
It sounds like open adoption, even though I can imagine the adoptive parents feeling insecure, it could still be a really good option for the child. No kid wants to feel they were abandoned.
