Just figured out that the Sonos stereo player I've had for years can be voice activated. "Hey, check this out," I say to the dog. "Sonos, play classical music!" He looks at me expectantly. Nothing else happens. "Hey Sonos, play classical music!" I say, more loudly in the direction of the speaker. The dog tilts his head to see who I'm talking to. Hayden suddenly blares across the room. "Cool, huh?" I yell to him above the symphonic din. He curls up in a ball on the sofa unimpressed. "Hey Sonos, volume down," I shout. The music retreats into a background feature. The dog shuts his eyes and goes to sleep. "Ta-da!" I mutter, and turn off the light, leaving the dog to Hayden.
