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 single 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 she had made a mistake fifteen years ago. She told me she had been the manager of a certain grocery store in the neighborhood where I grew up, and she asked me if I remembered the egg cartons. Then she related an incident and I began to remember vaguely the incident she was describing. I was about eight years old at that time, and I had gone into the store with mother to do the weekly grocery shopping. On that particular day, I must have found my way to the dairy food department where the incident took place.
There must have been a special sale on eggs that day because there was an impressive display of eggs in dozen and half-dozen cartons. The cartons were stacked three or four feet high. I must have stopped in front of a display to admire the stacks, just then a woman came by pushing her grocery cart and knocked off the stacks of cartons. For some reason, I decided it was up to me to put the display back together, so I went to work.
The manager heard the noise and came rushing over to see what had happeneD、When she appeared, I was on my knees inspecting some of the cartons to see if any of the eggs were broken, but to her it looked as though I was the culprit. She severely reprimanded me and wanted me to pay for any broken eggs. I protested my innocence and tried to explain, but it did no gooD、Even though I quickly forgot about the incident, apparently the woman did not.
