Sleep not when others speak, sit not when others stand, speak not when you should hold your peace, walk not when others stop.

Let thy carriage be such as becomes a man grave settled and attentive to that which is spoken. Contradict not, at every turn, what others say.

Be not forward, but friendly and courteous; the first to salute, hear and answer; and be not pensive when it is time to converse.

Be not hasty to believe flying reports to the disparagement of any.

In some circumstances the success of the military operation may be prejudiced by our reluctance to destroy these revered objects. Then, as at Cassino, where the enemy relied on our emotional attachments to shield his defense, the lives of our men are paramount. So, where military necessity dictates, commanders may order the required action even though it involves destruction to some honored site.
