What happens to a shared memory when it's only shared by two people? The only evidence that it even happened at all is contained within the mind of another. Some of my best memories are when it was just me and one friend or girlfriend. Most of the time those people don't hang around for a lifetime so we leave the shared experiences with them - and only them. So much of my life has been about those shared experiences that I feel like there are pieces of me spread across the world. It's a little unsettling. I think it's unsettling because though we are the protagonists in our own narrative we are merely footnotes in another's narrative. Sometimes to be forgotten completely.
Our sense of self comes from our memories. Our friendships are from shared memories. So when those people move out of my life, they take a piece of me with them. How is it that some of our most intimate and intense memories can be shared with another only to later have them pass out of our lives completely? I believe that one reason that death, divorce, and breaking up are so difficult is that we can feel those shared memories leaving our minds and with it a piece of unrecoverable self. It really does leave a void or hole that can't be filled. This is why photos, home movies, and journals are so important because we can go back in time to ensure that our memories are real. Memories without reinforcement will fade or be distorted over time. That's why these tools of time travel are so important to us. If your home were to catch on fire you wouldn't save your big screen TV, you would save your pictures. It may as well be a part of yourself left in the fire to burn. Those tools of memories are that important to us. Why?
Sometimes life really is a madness shared by two. I believe it's why we are often reluctant to end even the most miserable of friendships or relationships. Each time we end one of those relationships it really does take a toll on us. As we get older many of the relationships fade - people move away, people die, marriages divorce - and we are left with what remains. Surely this contributes to dementia in later life. With no one left to remind you of who you are and of the experiences you've shared, you're left with a slowly fading send of self. Of course, there are physiological reasons for dementia and Alzheimer's but what is not clear is the cause. It's possible that a lost sense of self leads to this physiological response.
As I've gotten older I've noticed that I cannot recall details with the same clarity and sharpness that I once did. It makes me wonder how many of my shared memories have simply evaporated without contact with those with whom I shared them. There are thousands of reasons to reinvest in current relationships, apologies to lost loves, or ring old friends. This is just one more reason. Not only are your memories fading, theirs are, too.
