Article: At an airport I overheard a father and a daughter in their last moments together. They had announced her plane's departure. Standing near the door, he said to his daughter: "I love you. I wish you enough." "Daddy, our life together has been more than enough. Your love is all I ever needed. I wish you enough too, Daddy." They kissed goodbye and she left. He walked over toward the window where I was seated. I tried not to _ his privacy, but he welcomed me in by asking: "Did you ever say goodbye to someone knowing it would be forever?" "Yes, I have," I replied. "Forgive me for asking, but why is this a forever goodbye?" I asked. "I am old and she lives much too far away. I have challenges ahead and the reality is that her next trip back will be for my funeral. " "When you were saying goodbye I heard you say, 'I wish you, enough'. May I ask what that means?" He began to smile. " That's a wish that has been handed down from other generations. My parents used to say it to everyone." He paused for a moment looking up as if trying to remember it in detail, and he smiled even more. "When we said 'I wish you enough', we wanted the other person to have a life filled with enough good things to sustain them," he continued and then turning toward me he shared the following as if he were reciting it from memory. I wish you enough sun to keep your attitude bright. I wish you enough rain to appreciate the sun more. I wish you enough happiness to keep your spirit alive. I wish you enough pain so that the smallest joys in life appear much bigger. I wish you enough gain to satisfy your wanting. I wish you enough loss to appreciate all that you possess. I wish enough "hellos" to get you through the final "goodbye".
