This is a lifetime of good-byes. In our time, we will say good-bye to cherished people, things, and ideas. Eventually, we say good-bye to life itself with our death. Learn to say a good good-bye. Allow yourself to mourn each loss. As with a physical wound, the body has its own schedule for healing. It will tell you when it has healed.
