Recently I overheard a father and daughter in their last moments together at the airport. The airline had her departure and standing near the security gate, they hugged and he said, “I love you. I wish you enough.” She said, “Dad, our life together has been more than enough. Your love is all I ever needed. I wish you enough, too, Dad.” They kissed and she left. He walked over toward the window where I was seated. Standing there I could see he wanted and needed to cry. I tried not to him, but he welcomed me in by , “Did you ever say good-bye to someone knowing it would be forever?” “Yes, I have,” I replied. “Forgive me for asking, but why is this a forever good-bye?” “I am old and she lives much too far away. I have challenges ahead, and the reality is, the next trip back will be for my ___ ” he said. “When you were saying good-bye 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 for many generations within my family. My parents used to say it to everyone.” He for a moment, looking up as if trying to remember it in detail, and then he smiled and the following: “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 joys in life appear much bigger. I wish you enough gain to satisfy your wanting. I wish you enough loss to all that you possess. I wish you enough ‘Hellos’ to get you enough the final ‘Good-byes’.” Then he walked away, leaving me lost in thought.
