...when a coworker at the library asks:
-"Why the h*ll do we have this book in Esperanto?"
-"I don't know when/why purchased it, but I happen to speak it". (Then I read from the back cover, aloud.)
Another coworker joins:
-"I once studied it! If I had maintained it, we could have used it as our secret language!"

-Cerramos dentro de treinta minutos. (Yep, that was it.)
Half an hour later, one of the co-workers shows up with two tourists, and points in my direction.
Girl: -Are you the guy who made that announcement? I thought you were Spanish! (Glancing at the Polyglot Gathering t-shirt) Now I see that...you are a polyglot! He's a polyglot too! (pointing to her companion)
Guy nods and confirms: -Poligloto.

I was at a park with my mom and a niece and nephew. A woman jogs past us speaking into her phone in another language.
Mom: "What language was she speaking?"
Me: "No idea, I didn't hear enough of it.

Now I'm hoping to cross paths with this woman again and try to figure out what language it was, but I doubt this will happen.
