People disappear when they die. Their voice, their laughter, the warmth of their breath. Their flesh. Eventually their bones. All living memory of them ceases. This is both dreadful and natural. Yet for some, there is an exception to this annihilation. In some way, they continue to exist. We can feel them again. Their humor, their tone of voice, their moods. They can anger you or make you happy. They can comfort you. They can perplex you. They can alter you. All this, even though they are dead.
