The Collective Memory, Boomer Style
Coupling your memories can confuse - and enrich - aging boomers
It goes without saying that 40-plus years of marriage hold a lot of memories. What becomes less clear, as time pushes us relentlessly onward, is what those memories are - and whose. That funny line, "What's mine is mine, and what's yours is â€¦mine!" takes on new meaning when the "yours" and "mine" have been mixing this long, and are now decidedly cloudy.
"Barry [names have been changed to protect the innocent] says he's coming over. I'll make him his favorite, meatballs. "
"Barry hates meatballs."
"I thought that was Harry."
"No, Harry hates ham."
"No, he used to hate ham, until he married Mary. Now he likes it. Pan-fried, with scalloped potatoes."
"How do you remember these things, when you can't find the car?"
Between the two of us, we can pretty much puzzle things out. When he is surprised by a sweater that appears overnight on his side of the closet, I remind him that it was a Christmas present from one of the boys, nine years ago. It snowed like crazy that morning, doesn't he remember? When I can't find my car keys for the thousandth time, he knows where to look and hands them over, albeit with a big sigh, before he asks if I have seen his glasses case.
On a recent anniversary, I thought it would be fun to pull out our wedding album and see what we remembered. (First challenge: finding the album.) It didn't take long to go through the mostly standard shots of bride, groom, wedding party, cake. But the pictures prompted questions. Was Lucy there? When did Bob get married? No, they're not divorced. He died, I think. No, they moved to Arizona. How do you know? It was all in their Christmas card, at some point. Okay, enough. Let's go see a movie. We did that last year. No, that was two years ago. Really? Yes, we saw "Up in the Air." Did I like it? No. But you wore that sweater and you looked good.
For years, I've kept a journal. More therapy for me than anything else, it is now acquiring the gravitas of our historical record. Where did we spend our vacation in 1986? What was the name of our crazy neighbor in Virginia? Silly trivia, good times. Then I stumble upon a name that conjures up fear and loathing, and I can't remember why, and that's a good thing too. When he wonders whatever happened to so-and-so, and neither of us has a clue, mostly we let these answers go: in the here-and-now of our memory, many things simply do not matter anymore.
Often our intensely shared experiences - births, tragedies, weddings, illnesses - benefit from this necessary merging of our faltering memories. While he was focused on the bride's brilliant smile, I was watching the flower girl - our granddaughter - toss her petals and not trip. He remembers one son's home run; I remember another's role in a Christmas pageant. He hit a homer? He played Joseph? Who knew? He can't forget how bitterly cold it was the day his father died. I will always remember his last sweet words to my mother. We are each enriched by the details in the other's memory.
I take lots of pictures - so we won't forget, I like to think - but am not good at recording names and dates on the back. I should know better: I've got a boxful of photos of dead ancestors in my closet, nameless and dateless. So here we go again: when was this taken? Is this Harry or Barry? Where are we? Sometimes he knows, sometimes I do. When neither has a clue, I may make something up and jot it on the back. "Barry at the lake, 1989" works if the shot was taken at a distance and you can't really tell if it's Harry or Barry, and they aren't around to argue. Or maybe they don't know either. Nobody's getting any younger around here, after all.
