From what we’ve been told he never knew we existed. I don’t know if that’s true or not though and we don’t have his name to track him down. It’s not listed on the adoption papers we finally tracked down.
Sometimes I wonder if perhaps he has a feeling, knowing there’s something (us) here, he just can’t quite identify it. I’m guessing not many people think about their life and wonder if they have kids they don’t know about. I could be wrong. I don’t know.
