"That night our gracious hostess at the temple, the head priest’s wife, showed a few of us how to fold paper cranes to give as offerings of peace at the atomic bombing memorial in Hiroshima the next day. She explained that her father had lived through the bombing as a child, and that it had caused to her be born with a heart defect caused by radiation mutation, a fact she was unaware of until she nearly died while giving birth to her daughter."
