说话的艺术。 对于语言、人类的行为。 我们可以用任何的角度来解释， 以为我们有交集，但彼此其实却站在互不相交的平行线上。 原来没有语言，我们可以更真实的交流。 其实我们比想像中的不那么真诚。 Art of talk. We can explain about language and human behavior in every angle . We thought we have some intersection, but it isn't. Without the language, we can communication more sincerely. We are not as sincerely as we thought.
