So the other night, we're watching the movie Sixteen Candles. (Does that movie ever get old? I submit that it does not.) The scene is Jake Ryan looking around his empty living room after it has been trashed by party-goers. The camera pans to a close-up of the stereo and my 8-year-old daughter asks me, "Mom. What's that black stuff coming out of the stereo?" And I had to explain to her what a cassette tape was. Ouch.
