I've run a building materials store for seven years. Over three years, my own older brother took more than 200,000 yuan worth of materials on credit, always promising to pay me once his projects were finished. One day, he brought six clients into my store and publicly promised them they could pick whatever they wanted, with me covering the price difference. I placed three orders and an old ledger on the counter. Whoever made the promise would pay, and nothing would leave the warehouse until payment arrived. After I stopped supplying goods, my family blamed me for bringing up old debts, and even my wife urged me to release the goods first. I gave them just one answer: Brothers can show each other consideration, but accounts must be settled properly. A year later, when the final payment arrived, he hugged the ledger and said thank you. With the debt settled, the brothers could still sit down and share a meal.
