A holiday, a special night, a fabulous trip, a milestone. We all keep mementos from these and other events, but it is not their physical presence that pleases us. Their true value is in the memories they evoke. Some are happy, some are sad, but they all have strong feelings woven into them, like a tightly interlaced network of emotions that continue to anchor our memories and the feelings they produce when conjured up by a song, a fragrance, or some long forgotten memento that had been safely tucked away in a golden trinket box.
