A couple of weeks ago, I flew SFO-FRA on the UD of a 747. I took the window seat, and in the aisle was a tech executive connecting on to Bangalore via LH. We had some nice chit-chat about the 747, Polaris, and travel to India over dinner, and then drifted off to sleep and said our goodbyes the next morning.
A week later, I was flying back to SFO, same seat on the UD, and when I came down the aisle, I saw the exact same gentleman occupying the exact same seat next to me as on the eastbound TATL.
What are the odds of this? We both agreed that it was the first time it had ever happened to us!
