I expect many of us have come across these, at least once in our lives......
My story....
I travel to Malta a lot, and a few years ago, on the plane back to England, I sat next to a woman about thirty five. We started engaging in small talk, like you do, and she mentioned that she was English, lived in Malta but had married a Maltese man, who owned a small sports shop on the island.......she went on to say she was travelling back to Lancashire for her father's seventieth birthday celebrations, he was in the furniture industry, extremely well off, and was having a marquee erected in the grounds of his house.
I asked what company it was, and it turned out it was fairly local to me, and I had bought some stuff from her dad's firm on several occasions....
We arrived home, I bade her farewell, and thought no more about it.
Then, around nine months later, I was on another flight returning to Malta, and this time sat next to an older lady, and we started chatting......it turned out her husband was in the furniture business, and she was going to Malta to visit her daughter, who was married to a Maltese man who owned a small sports shop...........
This was NINE months later, there were around 250 seats on each plane, I, or they could have sat anywhere....
I said "You are not going to believe this. I'm the father of your new Grandchild"..............
