It's a gateway. A portal to a time of all of our lives that we remember. Memories past. Recollections of the best things in our life. Of simpler times, times when we could enjoy life. But it also reminds us of our mortality, and how we cherish things, to the point of losing ourselves when we can no longer enjoy its presence. It reminds us of the things we truly cling to, and the events that define us, and make us ourselves.
