One day, a cat secretly stole the fish kept by its owner and started eating it. Just then, the owner came and saw it. The owner angrily asked, “Why did you steal my fish?” The cat then said very cunningly, “I didn’t actually steal, I was checking if the fish were good!” The owner laughed at this excuse, but realized that the cat was lying to cover up his mistake. This incident teaches us that if you make a mistake, you should admit it, because the truth cannot be hidden with excuses and it also destroys trust.
