    There are many important people in my life, and one of they I'll never forget.

    I met him the last summer. He, about twelve years old, short and sun-burnt. He was selling balloons on the sideway when I met him. I was curiously and asked him," Why do you do business at such a young age?" He said he was not doing business but raised money. He wants to donate the money to the poor villages there children needed help. I was surprised and ashamed. I bought much balloons from him and asked him to keep the changes. I should learn from him to being a helpful person.
