This refers to when two or more people encounter each other in completely coincidental fashion. You might notice your old classmate from three countries away is now your waiter in a place you had no reason to expect them in, and you might say “wow, what a small world”. You might notice two people who you know from completely different spheres miraculously know each other. You might recognize by chance that your penpal has made a cameo at a venue you’re at.
But what was your most profoundly coincidental encounter?
Not mine, but my dad’s that I was there to witness.
It was summer (90s) and we were all camping at a lake. My sister and I were playing with some kids while my dad was chatting up the other kids’ dad. Just as I was getting out of the water I hear the other dad exclaim “you remind me of a guy I used to know called [name]!” My dad laughs and says “I am [name].” Turns out they used to go to school together decades before.
It’s stuck with me all these years, and has somewhat been turned into an inside joke within our family.
