Some places and moments have this void quality to them. As if they do not strike in you a connection to the present, but rather the opposite. They act as a portal to another time and location, another memory. The beauty of placeholders is not in what they seem to be, but in what you populate them with. The memories you chose to relive there.
"He liked the fragility of those moments suspended in time, memories whose only function was to leave behind memories."
"Every memory, no matter how remote its subject, takes place 'Now,' at the moment it's called to the mind. The more something is recalled, the more the brain has a chance to refine the original experience. Because every memory is a re-creation, not a playback."
