Perhaps, each of us has an unknown corner in our hearts. As night fell, we hid in that corner, and no one could recognize us. Just like you, classmate. I don't know who you are or what grade and class you are in. But I know you have lost your integrity. Confucius, an ancient educator and thinker in China, once said, "People without faith don't know what they can do." It is the basic morality of being a man.

Remember that day? I lined up at the school gate to get ready to enter the school. You are walking up and down in a corner in a hurry. I saw it, so I hurried forward and asked you what was going on. You said, "I, I don't have a red scarf, so I can't go to school." You can borrow one yuan to buy a red scarf, and I will definitely pay you back tomorrow. " When I touch my pants, I have exactly one yuan. I gave you a dollar without hesitation, because I believed you.

But today, I saw you from a distance. I didn't pat you on the shoulder to pay you back. I want you to find me and change my money yourself. You pretend you don't know me and walk forward without looking back. I thought you didn't see me, so I came to remind you about paying back the money. You said impatiently, "Who owes you money? Do you owe me an iou? " I'm disappointed that I completely erased you from my memory. Classmate, what I care about is not that one yuan, but your integrity. Give you an encouraging word: honesty is the best coat of people's hearts.
