Goats took unique vows of silence. One goat might take a mutual vow with a sibling or friend, while another might never speak. They each had a personal reason for their choice.
Though different, each vow allowed them to focus on listening, observing, anticipating and servicing the needs of others. They connected without words.
The foolish thought goats dumb or inferior, but in truth, they were a very wise species sought out for council. That is, if they were willing to speak. If a goat gave you council, it was a great gift, because they rarely did.
