the last leave

When  having a firm belief, we will be more strong. If the littler girl had not noticed "the last green leaf", if the old man had not agree to help draw a beautiful leaf on the vine, the little girl must have been died. Excerptan  for that, the old man was a great man. At first, he think the little girl's idea and thought was ridiculous.However, they decided to rebuilt and strenghen her belief at the cost of his life.It shows us an another theme of the article--helping others is a meaningful thing. The little girl's life is a continuation of the old man's life.
