I still feel like this is mostly a "happy coincidences" thread, but have a story regardless:
Back in 2006 I got pretty badly beaten up in Vietnam. Ended up going back to Bangkok, and after leaving hospital, went to go change my flight home to bail out. The travel agent was closed that day though, so I ended up just drinking some beers on a rug on the street with some random people. That evening, I got an email from my ex girlfriend, who was in China, so ended up booking a flight there instead once the office opened again, and got back together for several more years. Thought that was a sign of some sort, as any other day, I'd already have been heading home.
After breaking up from that relationship 5 years later, I ended up going to Taiwan, and sent a message to one of the guys I was drinking on that rug in Thailand with, who had a bar there. Went to visit him, and and ended up with one of his staff, who is now my wife. She still to this day is thankful that I got beaten up in Vietnam so we met in a very roundabout way
