面有点污，人人匿笑，而已不知，有告之者，无不忙忙拭去。若曰：点污在我，何与若事？必无此人情。至告以过者，何独不然？
脸上有个污点，别人见了都暗自发笑，而自己还不知道，一旦有人直言相告，马上就用手拭去。如果还说：「我脸上有污点，与你有什么关系？」就不合乎人之常情了。可是当别人指出自身的缺点错误时，人们的态度为何就不是这样呢？
出自《道德经》，忘语在作品中引用，表达天地无情的世界观。
The first step in liquidating a people is to erase its memory. Destroy its books, its culture, its history. Then have somebody write new books, manufacture a new culture, invent a new history. Before long the nation will begin to forget what it is and what it was. The world around it will forget even faster.
