当我们加入一场谈判甚至是辩论时，我们首先要做的是感谢对方，这并不是一种冠冕堂皇或者约定俗成的姿态或者仪式，而是为了庆幸双方尚有共识。在缺乏任何共识的情况下，连最激烈的辩论都会显得多余，剩下的解决方案只能是冷漠或兵戎相见！

When we join a negotiation or even a debate, the first thing we do is to thank for the participation of the other party. This is not a high-sounding or conventional gesture or ceremony, but to celebrate that the two parties still share some consensus. In the absence of any consensus, even the fiercest debate will be superfluous, and the remaining solutions is unconcern or war!
