Mine isn't Disney-related and is very complicated, which makes it even more freaky for me.
I grew up in the military and went to middle school in Greece. A friend (M) from that school found me on fb. M was living in the same city as I was at the time, but moved to London before we met in person. I sent M a birthday message and his response to me was that he'd just been to Turkey for his birthday and was in line for a museum or something and got to talking with the people behind him. He ended up meeting someone (D) who lives in San Francisco, and, through the course of their conversation, they realized that they both knew me. I had met D in Argentina when we both went to Antarctica to run the marathon.
To summarize, a guy I met in Greece 30 years ago, who is now living in London, went to Turkey and met a guy, who now lives in San Francisco I met in Argentina on our way to Antarctica. It still gives me shivers, just thinking about it!
