One day, I picked up my daughter Lingling from school and went to the supermarket for a few things. I was hoping to be in and out quickly.
I found a short line with just one person in front of me. It was an old woman, and she was paying for her things with only coins（硬币）. After a long day at work, I thought the woman was very terrible.
But then I watched a young salesman. He helped her count her coins, ever so kindly taking them from her shaking hands. He repeatedly said to her, "Yes, ma'am（女士）."When she asked if she had enough money to buy a bag, he told her she did. Then he walked over two lines and got one for her. This salesman wasn't angry at all. He was patient and kind.
As I was watching him, I saw Lingling was, too. I realized my daughter was learning an important lesson from a stranger.
When the woman was finished, the salesman began ringing up my things and thanked me for my patience（耐心）. I thanked him, too. I found the manager and told him about the salesman's kindness and patience.
Then we left the supermarket with a full basket, but also with a heart full of thankfulness for such an important lesson.
