Ryan's Dream
When my son Ryan was six years old and in the first grade, his teacher, Nancy, talked to the class about developing countries and how they could help people, particularly children, in other parts of the world. The teacher told the class that seventy dollars would buy a well in developing countries. When Ryan heard people died because they didn’t have clean water, he was deeply affected. He came home that day and insisted he needed seventy dollars for class the next morning.
