Childhood is one thing you have to keep in your heart. When we were children, we dared to dream about everything we needed. On the other hand, when we grow up, we may forget the dreams in childhood. In as much as, the responsibility in adult makes we abandon our dreams in the past. That is to say, the time makes us forget our ambition. I think we should hold the dream because it has worth. Sometimes, I miss the smile and laugh in the past. Because, the kids have a sincerely smile and they can laugh about simple stories.
