Mini Story to Lock It In

Imagine a village centuries ago where a weaver is famous for cloth that never fades. He insists on dyeing the wool first, before spinning it. The color sinks in so thoroughly that, years later, even after sun and rain, the cloth is still bright. The villagers start saying, “If you want color that never changes, you want wool that’s dyed in the wool.” Over time, they begin using the phrase for people too: the neighbor who never changes his political stance, the friend who will always back the same team, the aunt who will always drink tea and never coffee. Their “color” (beliefs and character) is set early and never really fades.
