Even dunces who keep quiet are thought to be wise; as long as they keep their mouths shut, they’re smart.
Knowledge flows like spring water from the wise; fools are leaky faucets, dripping nonsense.
Loners who care only for themselves spit on the common good.
Fools talk way too much, Chattering stuff they know nothing about.
Fools on the road have no sense of direction. The way they walk tells the story: “There goes the fool again!”
Overwork makes for restless sleep. Overtalk shows you up as a fool.
