I was on a bowling league many years ago. Husband #2 was boyfriend at that time. He worked shift work at a prison....6 months on each kind of shift. So he had off one league night and came to be with me. I looked around one time and he was off down a few lanes over, standing back talking to my co-worker. Turns out they had graduated together in a small school over 1000 miles away 30 years before.
My folks were on a plane that had a layover in Denver. The plane had some engine trouble so they were told their dinner and overnight stay would be paid for by the airline.(those were the days!!!). They were required to go to a certain restaurant in the airport for the dinner. Table space was tight, so they shared tables. The man sitting with my folks had a deep southern accent. After some discussion it was discovered he was my mother's 2nd cousin from DeKalb, Georgia. My folks lived in Oregno at the time. Small, small world!
