原文最后一段话是这样说的：
This should suffice, my friend. To say more would be too much, because it would only foster the fear of the human beings of Earth, which should not be, however. So keep silent on all the further explanations that we have given you.
其中，it would only foster the fear of the human beings of Earth（再多的解释会引起人类恐慌），我觉得很根本就是暗示2012确实会有大事发生，大家应该做好心理准备。
