Morning wisdom

Just as a gaffe must be true, it appears that an aphorism must be false. For example, "A watched pot never boils." I've checked that one out, and I'm here to tell you that it does not pass the 100% truth test. A true thing we might have said is, "An empty kettle never boils" or "If you've left an empty kettle on the burner for a significant amount of time, it's probably best to turn down the heat and wait a few minutes before trying to add water."
