I have finally come to the realization that I was not a blank slate as a baby that was waiting for an identity. My identity was hard wired. I share 50% of my DNA with my birth mother, and the similarities with her and my siblings are shocking.
The one thing we are laughing about is how we think exactly the same about politics and religion. Almost identical philosophies. Our tastes in almost everything are the same. Sense of humor. Not to mention finally being mirrored with physical sameness.
