Depends on how much money he earns.
Actually it wouldn't surprise me at all....my father was in the military and claimed he had a child every where he ever went.
I'd be shocked, stunned. I'd want blood tests. But if it turned out to be true, I'd give him my sister's name and send him to meet her.
No one would claim to be from my family and be sane. I asked my mom and dad if I were adopted and they said no . . . I cried for a week.
I would want to meet and greet him. I would not want to give up any information and even if he sort of proved it, I still wouldn't believe him, more than likely. It would take a lot to convince me.
Something similar did happen like that a few years ago, luckily, after a few questions, he'd got the wrong person. To tell the truth, I was a bit disappointed, I was hoping he'd have the news of a distant relations death, and I'd been left a fortune
I have three older brothers who died before I was born. If one was alive and had just been given up for adoption I would cry and jump around and ask when we could meet and welcome him with open arms. I would want to know where he had been for the past 43 years and what had happened in his life.
Pictures, or it never happened.
