My neighbor got a new golden retriever. Every time the neighbor picks up a piece of food, the golden retriever looks at the food. Then looks at the neighbor. Then looks at the food. Then looks at the neighbor. The neighbor says, 'He's so communicative! He's telling me something!' I said, 'He's telling you to give him the food. He's been telling you to give him the food for forty-five minutes. He's not communicating. He's negotiating. And he's not making any concessions.'
