Right Place, Right Time
One year, during the off-season, my girlfriend and I went on vacation to Miami Beach. We were headed back to the condo, but we missed our bus. We got on the next bus.
On the bus, we saw my step-brother and his wife, who lived in Maryland. We had no idea they were even on vacation. We just happened to be in the same city, at the same time, on the same bus. Story credit: Reddit / lordnecro
