I remember Zola said: "Broken promise is failure." This matter is related to a person's sincerity.

It happened one day when I was in fourth grade. That afternoon, I finished my Mathematical Olympiad class and was about to take the bus home. I came to the station, opened my wallet, took out my change, and counted it. Oops, it was only one yuan and eighty cents, still two cents short. What should I do? I looked through my wallet, and there was nothing in it except a ten-dollar bill. I couldn't put a ten-dollar bill into two dollars! How about going to a small shop to find change, but there weren't any shops nearby. I looked around and saw a bus driving over. I don’t have time to think too much now, why don’t I just get one and eight dollars? Mine are all coins and the driver can’t tell. I’m secretly proud of my “good idea”.

I got on the bus with the crowd, stuffed all the money in without the driver paying attention, and then sat down in a seat next to the driver. It was done flawlessly and I felt at ease. I was very happy. I saved myself money, and it felt like I had done a great thing. At this time, an old man appeared in my sight. He was wearing a set of white overalls. He was holding a cane and a newspaper in his left hand. He was taking money out of his pocket with his right hand. They were all 10 or 20 cents. Haha. , 80% like me, want to save money! I thought to myself. But what surprised me was that the old man did not put the money that he had counted in advance into the cashier box immediately. Instead, he put the money in his hands and counted it carefully: "Fifty cents, seven cents, one yuan, two yuan, um, just right." Counting as he cast, he counted softly in his mouth. Suddenly, I was stunned, and suddenly realized how shameful my behavior just now was, and I was still so happy. The driver uncle worked so hard to make money, but I still cut corners, not even letting go of the few cents.

Since then, "Breaking trust is failure." This famous saying has been deeply imprinted in my mind. I often use it to remind myself, and it has become my most unforgettable saying. .
