One of the qualities that most people admire in others is the willingness to admit one’s mistakes. It is extremely hard sometimes to say a simple thing like “I was wrong about that ,”and it is even harder to say, “I was wrong ,and you were right about that.” I had an experience recently with someone admitting to me that he had made a mistake fifteen years ago .He told me he had been the manager of a cartons (纸箱).Then he talk of an incident and I began to remember the incident he was describing.

I was about eight years old at the time , and I had gone into the store with my mother to do the weekly grocery shopping. On that particular day, I must have found my way to the food department where the incident took place.

There must have been a special sale on eggs that day because there was a big show of eggs in dozen and half-dozen cartons. The cartons were put three or four feet high. I must have stopped in front of them to admire the show. Just then a woman came by pushing her grocery cart and knocked off the pile of cartons. For some reason, I decided it was up to me to put the cartons back together, so I went to work.

The manager heard the noise and came rushing over to see what had happened. When he appeared, I was on my knees checking some of the cartons to if any of the eggs were broken, but to him it looked as if I was the person who was to blame .He scolded me loudly and wanted me to pay for those broken eggs. My face turned red and I tried to explain, but it did no good. Even though I quickly forgot the incident, but the manager did not.
