Lesson 45 A clear conscience
The whole village soon learnt that a large sum of money had been lost. Sam Benton, the local butcher, had lost his wallet while taking his savings to the post-office. Sam was sure that the wallet must have been found by one of the villagers, but it was not returned to him. Three months passed, and then one morning, Sam found his wallet outside his front door. It had been wrapped up in newspaper and it contained half the money he had lost, together with a note which said: 'A thief, yes, 'but only 50 per cent a thief!' Two months later, some more money was sent to Sam with another note:' Only 25 per cent a thief now!' In time, all Sam's money was paid back in this way. The last note said:' I am 100 per cent honest now!'

练习感悟：
这个课时……暴风简单……差不多是一个冷笑话了吧。
偶尔会惶恐，说不定哪一天，它的难度突然拔高就比较麻烦了。开个玩笑，不过应该也很有挑战性吧。
