In her book The Preaching Life, Barbara Brown Taylor tells of a conversation she had with a friend who grew up on a sheep farm in the Midwest. According to him, sheep are not dumb at all. "It is the cattle ranchers who are responsible for spreading that ugly rumor, and all because sheep do not behave like cows. Cows are herded from the rear by hooting cowboys with cracking whips, but that will not work with sheep at all. Stand behind them making loud noises and all they will do is run around behind you, because they prefer to be led. You push cows, her friend said, but you lead sheep, and they will not go anywhere that someone else does not go first. Their shepherd-who goes ahead of them to show them that everything is all right."

Sheep know their shepherd and their shepherd knows them.

He went on to say that "it never ceased to amaze him, growing up, that he could walk right through a sleeping flock without disturbing a single one of them, while a stranger could not step foot in the fold without causing pandemonium."

Sheep & shepherds develop a language of their own.
