Now this is interesting “ the only one who felt the same way as me was my wife.”
It’s strange that the wife seems to be forever airbrushed from the believer’s narrative.
You are cherry picking the bits you think suit your theory and ignore the bits that contradict it. "Oh, look, his wife agrees too". Agrees with what? That the person looked like Gerry? That her husband "might" have a point? Or was it maybe that she was the only one who didn't say that he was definitely mistaken?
Why are you ignoring that other members of his family who saw the man disagreed with his assessment that it "could" have been Gerry?
His wife doesn't even make a statement about it. She didn't even go to Portugal when the others did to give their descriptions of the man they saw. How do we even know what she thinks she saw, how good a look she got, how much she remembers, how much she could describe of that person?
There were 3 people who gave detailed descriptions of the man they saw to PJ. Martin, his son Peter and his 12 year old daughter Aoife. So, of the 3 people that we know got a decent look of this bloke, 2 of them don't agree that it could have been Gerry McCann. The one who does is possibly only 60% sure... based on nothing but a mannerism he vaguely recalls as being similar 4 months after the event... an event that he didn't even remember at the time... not until his son Peter asked him whether he'd dreamt them seeing a man carrying a girl.
