I stumbled upon words I hated: apparently Ben Walden was my bio-dad.
I greatly dislike the ways of talking about biological parents as differentiated from my PARENT parents. I wish we had a different vocabulary, although I can’t think of what it would be. I do tend to say “birth-“ or “bio-mom,” “bio-dad,” and “adopted mom and dad,” but I also almost always add, “my real mom and dad,” because that is who they were.
The other two were just a tiny part of creating me. (Well, the bio-dad especially…of course, the bio-mom had a longer commitment of the pregnancy.) But my actual for-real parents were there for every moment of my life.
