I unexpectedly ran into smmc while grocery shopping. At a distance, I mistook her for trystan_laryssa with an unfamiliar tall, be-hatted entourage, but it turned out that she was someone completely different, someone I may have met in person but it's not entirely clear where, or perhaps (likely) we haven't. We chatted and caught up on stuff in any case.
On the way home, it finally registered that the entourage reminded me of someone I used to be acquainted with back in Fairbanks, one of the Games of Adventure (duct tape sword) guys.
It's a small world, even when you turn out not to know the person you just ran into.
