"My male cousin did one and found a female cousin we did not know about. He reached out to her and apparently our deceased uncle was good friends with her mother. Mom wanted a baby so uncle got her pregnant simply as a sperm donor.
Female cousin lived a few blocks away from my grandmother. She had met her a few times going around selling Girl Scout cookies or something. My grandmother had no idea that she was buying cookies from her granddaughter."

Father had a hook up in college, the young lady being at a Catholic college, dropped out to bring the baby to term, which was given up for adoption (the 60's). My (half) nephew reached out to us to try to talk about his mother (my half-sister) that had suicided from a rough life in the foster system and then drugs.... The tests are not ruining lives, sh#tty people are ruining lives (father included (wear a raincoat for f@#ks sake)).
