One of our most coveted possessions is an electric tea kettle (not pictured; it’s too grungy to photograph) that automatically shuts off once the water has boiled. And one of my favorite sounds of the morning is the steady crescendo of boiling water the kettle produces. It’s barely perceptible at first, a quiet hiss, but 20 seconds later, it’s rumbling enough that I can hear it from the top of the stairs.

It’s a friendly, promising sound. It doesn’t demand immediate attention, as a whistling tea kettle does. The boiled water will stay hot for several minutes if you don’t reach it right away. Or if you’re a purist (as I am), you simply switch it on again to heat the water to the proper just-boiled temperature before warming the pot and making the tea.

I could pick our tea kettle’s sound out of a aural lineup any day. It says: you are not alone on this cold winter day. Soon you will curl your fingers around a mug of hot tea, sweetened with a splash of milk and way too much sugar. You will sip, you will wake up, you will take on the day.
