Memory flashes

Tonight, I've been thinking about people and circumstances long since passed. A person who was a mutual acquaintance of my parents and our next-door neighbor; an old hotel in town which may not even be there now and if it is, it probably isn't the best in the area; the old AM rock station I used to listen to (yeah I said AM rock station) and others I can't recall right now.
I'm not sure what's been sparking this, but I guess it's part of the healing process of helping me remember that even though a great deal of time has passed since my parents died, the world they lived in isn't completely dead, even though it's changed a great deal.
Lord, help us understand the purpose for old memories and let us live out your plan and passion for it.
What old memories to do you have and how much do you wish to understand them?
