Years ago, I seem to recall an internet video. Was it Swedes listening to a car radio? I can't quite recall. Two parents in the front seats of the car. Two young girls sitting in the car's back seats. The video was a commercial for learning English. In the commercial, the two children understood the, um, shall we say, not so family friendly lyrics being played over the radio in English. The parents didn't understand the lyrics. The mom began to rock her head and snap her fingers to the music. The two children snicker at each other. Then the commercial fades to text that says Learn English . . . and name of a company that offers lessons.
