The following conversation took place in my living room. With my wife and son as witnesses. With our freshly-laundered jiu-jitsu uniforms in plain view (and previously commented upon by the subject).
Oblivious: "So, when are your jiu-jitsu classes?"
Me: "Monday & Thursday, 6 pm for kids, and 7 pm for adults."
** two minutes pass **
Oblivious: "Yeah, this town is a jiu-jitsu desert... but you know that... there's nobody around who teaches unless you go all the way to Nashville."
My wife's eyes were about to pop out of her head with a "WTF" look.
