There is a deep sense in which we are all ghost towns. We are all haunted by the memory of those we love, those with whom we feel we have unfinished business. While they may no longer be with us, a faint aroma of their presence remains, a presence that haunts us until we make our peace with them and let them go. The problem, however, is that we tend to spend a great deal of energy in attempting to avoid the truth. We construct an image of ourselves that seeks to shield us from a confrontation with our ghosts. Hence we often encounter them only late at night, in the corridors of our dreams.
