there is a loudspeaker in town that broadcasts local trivia nightly.

tonight:  “Good Evening,  tonight, the Z- family’s pet dog, Chuusho, noticed that sake in her water dish smelled of acetic acid, meaning that it had been there awhile and was safe to drink, because the acetobacter had completely converted the ethanol to vinegar.  She had to pick up her owner from the onsen and she didn’t want to drive drunk.  Good Night and Sleep Tight.”
