When a man says he approves of something in principle，it means he hasnt the slightest intention of putting it into practice.
Ground Rules
One of my favorite teachers at Southeast Missouri State University in Capecape n.海角， 岬 Girardeau was known of his droll sense of humor. Explaining his ground rules to one freshman class， he said， “Now I know my lectures can often be dry and boring， so I dont mind if you look at your watches during class. I do， however， object to your pounding them on the desk to make sure theyre still running.”
当一个人说他原则上赞成某事时，那就是说他根本无意把那件事付诸实施。
基本原则
位于吉拉多海角的密苏里东南州立大学有一位我非常喜欢的老师，他奇特的幽默感很是出名。在对一个新生班级讲解他的基本原则时，他说：“我知道我的讲课可能经常会枯燥乏味，了无生趣，所以如果你们在上课时看表我并不介意。不过我坚决反对你们将表在课桌上猛敲看它们是不是还在走。”
