He had worked in a car factory for five years. Then an accident left him disabled. While listening to his story I realized that he had experienced     4     a lot in his life. I told him that although he was physically     5     disabled, his heart was strong, and he could always depend on it. I offered him some money to buy food and drinks     6     and then he went home. I have learnt that if you say a few good words and offer a little help to others, it will not only bring happiness     7     to you, but it will also be in people’s hearts forever.
