It was a sunny Saturday in Oklahoma City． A proud father Bobby Lewis was taking his two boys to visit a museum． He walked up to the penson at the ticket office and said， "How much is it to gei in？"

The person replied， "3.00 for you and 3.00 for any kid who is older than six． We will let them in free if they are six or younger ，How old are they？"

Bobby replied， "One is three and the other is seven， so I guess I owe （应给）you ＄6.00. "

The person at the ticket office said，"Hey，sir，did you just win the lottery(彩票) or something? You could have saved yourself ＄3.00． I wouldn't have known the difference．" Bobby replied．" Yes， that may be true， but the kids would have known the difference．"

As Ralph Waldo Emerson said， "Who you are speaks so loudly I can't hear what you're saying．" In challenging times when ethics （伦理） are more important than ever before， make sure you set a good example for everyone you work and live with．
