I pull the car over to the curb so Dotter, Bean and I can view the beautiful Christmas decorations on this one particular house. It had strings of lights everywhere... and a sign posted that directed us to tune our radio to a particular station. Sure enough the lights dance and jump in time to the music. It's beyond beautiful. There wasn't a section of this home and yard that didn't have a light flashing, mesmorizing... after several quiet moments Bean perks up: "Hey! Listen! The lights match the music! That's cool!" I tell her they're supposed to. That's the point. They coordinate the lights to turn on and off in time with whatever song is on the radio. She was obviously impressed as she sat open-mouthed, watching. After a few minutes she asked, "Doesn't his arms get tired? All that plugging and unplugging? I'd get confused if it were me."
