The first goal of this negotiation is determining what everyone wants from a conversation. These desires are often revealed via a series of offers and counteroffers, invitations and refusals, that are nearly subconscious but expose if people are willing to play along. This back-and-forth can take just a few moments, or last as long as the conversation itself. And it serves a crucial purpose: To help us find a set of subjects that we are all willing to embrace.
