It's natural for you to feel sad when some people are not polite to you. However, we should try to understand others let the sad moments go.

Last Sunday, when I was shopping, I met old friend of mine, Betty. She was looking for something. After a short talk with , I knew that she worked as a cashier (收银员) at a nearby store.

    It was clear that she was not happy. Sometimes the customers (客人) were not (friend) to her at the store. She said that it even made her a bit nervous she worked.

    "Well, I think I can understand," I said. "You know, I was a nurse before, and I had sad moments as well. Sometimes patients (病人), their family (member) or doctors weren't polite, but I tried to understand them. I let the sad moments go and just tried to do my job (good)."

    She looked a bit relaxed after (hear) my words. "How kind and friendly you are!" she said. We (talk) for another while and then she headed back to the store a big smile on her face.

    Try to understand others, and the world will be better.
