In the evening, with the windows open to the crickets’ songs, my daughters sit on the couch, doing homework together, while I read about the 1918 pandemic and knit.

Half-listening, I hear my daughters figure out the answer to a chemistry question, googling definitions. Decades beyond my own high school science classes, I’m no good here. Inevitably, these discussions always remind me of my adolescent years — well before google — when my father was the in-house reference for anything from trigonometry to weird geography questions.

Not so, in this house. I advise the girls to call my brother.

But as I listen, I realize they’re piecing through an interesting problem about change on the molecular level, and my youngest notes that change is the one constant.

It’s a particularly poignant observation for a 15-year-old, and I lay down my knitting and take a walk in the darkness around our house.

This week — heck, these months — seem filled with stories of people around me whose lives are in upheaval. These are all people I know and care about, in varying degrees. I keep thinking how, on a political level, so much misery is caused by exploiting the weakness of others. So, too, in our own personal levels, where so much of our energy often jockeys for a position of strength, betraying a marriage, a confidence, a professional relationship.

Meanwhile, change is the one constant. Surely, if nothing else, that could be a theme for 2020.

And yet, perhaps, it’s not.

In the darkness, I stand near the woodpile, breathing in the scent of sap and fresh wood, of damp soil turned up. Our cat sits on the windowsill, peering out at me. Overhead, the Milky Way spreads across the sky. My daughters’ voices drift through the screen, figuring out their answers, laughing a little — for the moment — happy.
