Shortly after my mother’s death, about three years ago, my sister gave me a gift: a pair of earrings she had had made from my father’s monogrammed sterling silver cuff links, still nestled in cream velvet in their original oval purple velvet box. I was touched and delighted by them, excited to wear them, and to have this keepsake.

One winter afternoon, I wore them for the first time, and went shopping with a friend. We had fun, wandering from one shop to the next, and spending a fair amount of time trying on hand-knitted hats. I guess our ears were cold.

It was about an hour later that I realized I was wearing only one earring. The mood of the afternoon was instantly altered. I tried not to show how upset I was, reminding myself that it was just a thing. We retraced our steps, I went through all the hats, gently shaking them, and looking for something caught in them. I crawled on the floor of the shop. Hopefully, I left my name and number with several of the stores we had been in, but I never heard from anyone. It was gone.

I never said anything to my sister. I put the one cufflink/earring away in its ancient purple velvet box, and promised myself that someday I would have it made into a necklace. But I felt sick at the loss.

Yesterday was my birthday, and although I try hard to be grateful to be having a birthday, I spent the day fighting off a case of melancholy. I felt the passing of time, the shortening of the horizon, and a soft, persistent nostalgia for my late parents. Don’t misunderstand: there were cards, and gifts, and flowers, and phone calls, greetings from friends and strangers, a snowstorm, and best of all, an advance copy of my new novel in the mail. Nevertheless, I spent the day in an uncharacteristic lethargy, unable to accomplish much of anything.

Toward the end of the day, though, I bestirred myself to straighten our dark, cozy library for the evening. I had recently redone the room as a surprise for my husband, and had emptied the shelves and cleared all the surfaces before and after I painted. The little brass tables had gotten wiped and polished, and even the bottles on the bar cart had been dusted. I oiled the wood. On Friday, our cleaning lady went over everything again, so it all sparkled.

I lit a fire, and some candles, I put on my favorite Beethoven piano sonata, which reminds me of my father’s last days. Feeling both sorrowful and affectionate, I began stacking the week’s collection of books, papers, to make some room on the table, when something caught my eye. On the table—the table I had emptied and polished twice in the past week—was a small oval silver shape. It was an earring.

Unbelieving, I went to my bureau where the purple box was kept. The one earring was in the box. The other was in my hand.

I immediately texted my cleaning lady. Yes, she had found it in the couch, and forgotten to say anything.

But here’s the thing. In three years, the house has been cleaned many times. The couch has been vacuumed at least every other week. There is a perfectly rational explanation for how the earring got there. But it feels, to me, as if I had a visitation, and I can’t help but believe that on this melancholy birthday, as I listened to the music that brings him so vividly to mind, my father reached through the weave of time. Warmed and happier, I wore the earrings last night, ate cake, and drank champagne.

Wisdom tells us not to put too much value in things, or to choose mysticism over reason. But sometimes when we don’t expect it, everything shifts, the lines can blur, and the momentary mysteries we see instead make life’s realities both rich and beautiful.

It was a happy birthday.
