In spring, Xiaogang has planted a few pots of rose flowers. A month later, Xiao Gang was in a wheelchair to water the flowers as before. A wealthy wife came over and saw this beautiful rose flower. She couldn't help but say: "This month's flowers are beautiful!" Speaking of picking a rose flower, I admire the beautiful rose flowers and turn around. When Xiao Gang saw it, he turned the wheelchair to catch up. He solemnly said to his wife: "The beautiful flower is for everyone to appreciate. It is not for one person. This flower cannot be picked. Now you have taken off the flower, you have done something wrong. You should apologize to me.” The wife took out the money from her pocket and said to Xiaogang: “How much does it cost, I bought it.” Xiaogang said calmly: “Do you think that money can buy everything?” Oh, my face was suddenly red, and she said slyly: "I understand a truth." Then he put the flowers down. Xiaogang smiled and said: "Since you have understood a truth, I will give you this flower." The wife looked at the wheelchair carefully and looked at Xiaogang. He said with respect: "Thank you!" After that, the wife took the flowers away.
