    I work in a cleaning company. It provides house cleaning service. 

    One day, I got a call from a man named David. "I want to help an old man. Can I pay for it without letting him know?" He asked. David was a very kind man. He called us because he was worried about his neighbor, Mr. Smith. Mr. Smith was ill and he just came back from the hospital. His house was in a mess, but he couldn't do any housework. He didn't tell his children. David wanted to help Mr. Smith without bringing him any stress. And then we asked David what would happen if Mr. Smith would refuse to let us come into his house. "I have to at least try. I really want to help him," he said.

    Luckily, Mr. Smith let us in and our workers did a good job. Since we promised David not to tell Mr. Smith his name, we didn't tell too much to Mr. Smith. Mr. Smith was touched by the gift from someone he didn't know.

    Sometimes we don't expect to depend on others, because we are afraid of letting them get into trouble. However, there is always someone who cares for you and tries his best to help you.
