使贪

刘基

       客有短吴起于魏武侯者，曰：“吴起贪不可用也。”武侯疏吴起。公子成入见曰：“君奚为疏吴起也？”武侯曰：“人言起贪，寡人是以不乐焉。”公子成曰：“君过矣，夫起之能，天下之士莫先焉：惟其贪也，是以来事君，不然君岂能臣之哉？且君自以为与殷汤、周武王孰贤？ 务光、伯夷天下之不贪者也，汤不能臣务光，武王不能臣伯夷，今有不贪如二人者，其肯为君臣乎？今君之国，东距齐，南距楚，北距韩、赵，西有虎狼之秦，君独以四战之地处其中，而彼五国顿兵坐视，不敢窥魏者何哉？以魏国有吴起以为将也。周《诗》有之曰‘赳赳武夫，公侯干城’吴起是也。君若念社稷，惟起所愿好而予之，使起足其俗而无他求，坐威魏国之师，所失甚小，所得甚大。乃欲使之饭粝茹蔬被短褐步走以供使令，起必去之。起去，而天下之如起者，却行不入大粱，君之国空了。臣窃为君忧之。”武侯曰：“善。”复进吴起。

     April Fool's Day is supposed to be a day to play jokes on others in hopes of getting a good laugh and making one feel like a fool. However, the April Fool's Day of 2013 was quite different for my morn and me.

     That day my friend Jimmy and I were playing a game. I had dropped down from a bar(横木) many times in the past without ever having a problem, but that day the simple act of dropping to the ground became a nightmare(噩梦). I broke my arm.

Jimmy's dad heard my crying and rushed out to see what was going on. When he saw the

problem, he quickly put me into his truck and went inside to telephone my mom and let her know he would take me to the hospital. As that day was April Fool's Day, Mom was not buying it and really thought all this was a big joke. Mom was finally convinced(说服) by Jimmy's room. When she saw me, she broke down in tears because she felt so bad--she originally (起初) thought this was just a big prank(恶作剧).

      I guess one could compare this to the story of "The Boy Who Cried Wolf". Since I had pulled pranks before, it is no wonder that my morn didn't believe it. I as well as my morn was made to look like a fool that day. We both learned a valuable lesson.
