As soon as school was over, Tom walked out of the school gate listlessly. He walked on his way home in dismay. What should he tell his father? He thought to himself. Suddenly, he thought of a trick. As soon as he entered the house, Tom excitedly said to his father, "Dad, let's play games. You can't. " After that, Tom covered his eyes with a towel, signed his name on the paper with a pen, and then said to his father in a provocative tone, "Dad, can you do it?" Dad said, "Who said I wouldn't? You little devil will, and so will I. " After that, my father covered his eyes with a towel and signed his name on the paper with confidence like Tom. At this time, Tom quietly took out his exercise book from his schoolbag and put it carefully in front of his father, who was still in the dark and quickly signed it.
After signing a few more names, dad took off his towel and admired his masterpiece, while Tom was putting the signed exercise book back in his schoolbag. At this time, he felt that the big stone in his heart finally fell to the ground and could not help singing. Dad was a little puzzled after reading the signature and said, "I signed five names, why only four?" This is a mystery. Hearing this, Tom made a smug expression to his father, hoping that his father would not find out his "trick", otherwise the consequences would be even worse!
