One who knows when to speak will also know when to be silent. 知道什么时候说话的人，也知道什么时候保持沉默。 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
“It is better to remain silent at the risk of being thought a fool, than to talk and remove all doubt of it。” --- 摘自《Mrs. Goose, Her Book》，by Maurice Switzer；Forgotten Books，1907 |
