孔子曰：“侍于君子有三愆：言未及之而言谓之躁，言及之而不言谓之隐，未见颜色而言谓之瞽。”
1Confucius said, 'There are three errors to which they who stand in the presence of a man of virtue and station are liable. They may speak when it does not come to them to speak;-- this is called rashness. They may not speak when it comes to them to speak;-- this is called concealment. They may speak without looking at the countenance of their superior;-- this is called blindness.'
