I just found my long lost dad after 45 years. I last saw him when I was 5 when my parents split up. I knew 100% for definite it was him for a couple of reasons including I'd found a photo of him online linked to the information I'd found, so it was unmistakable.
I sent him an email talking about what I remembered about him and the places we'd been. I said that if he didn't want to reconnect that I'd understand but that I'd just love an email from him to see how his life had been and what he remembered about me.
He sent a message back saying that I'd got the wrong person and that he'd never been to those places. ...sadly I replied saying sorry I got the wrong person... I humoured him as I knew he wasn't interested. Has anyone else had something like this happen where the found parent isn't interested? I saw it happen once on a long lost family type show. I'm glad they showed it as it must happen occasionally.
