Train Man - Nakano Hitori
"What they did was something very simple: they offered to help somebody who needed help. It was a simple gesture stemming from a sense of common courtesy we all carry within ourselves."

It really is amazing how the power of encouragement and faith to a person can change their lives forever. These anonymous people weren't obliged to help Train but they did so because they really wanted to help him. There really is still hope in humanity.
