The role of listeners has never been fully appreciated. However, it is well known that most people don’t listen. They use the time when someone else is speaking to think of what they’re going to say next. True Listeners have always been revered among oral cultures, and prized for their rarity value; bards and poets are ten a cow, but a good Listener is hard to find, or at least hard to find twice.
