" Kindness toward strangers is rare in North Korea. There is risk in helping others. The irony was that by forcing us to be good citizens, the state made accusers and informers of us all. The episode was so unusual that my mother was to recall it many times, saying how thankful she was to that man, and to the passengers. A few years later, when the country entered its darkest period, we would remember him. Kind people who put others before themselves would be the first to die. It was the ruthless and the selfish who would survive. "
