I'm sorry I don't know who the original author was, but I thank my sister, Cathy, for sending me this story:
Recently, I overheard a mother and daughter in their last moments together at the airport. They had announced the departure.
Standing near the security gate, they hugged and the mother said, "I love you and I wish you enough".
The daughter replied, "Mom, our life together has been more than enough. Your love is all I ever needed. I wish you enough, too, Mom".
