Several weeks ago I had to come to the rescue of our pastor, who was trying to explain record players to a college student. She would not believe anything he said about 33s, 45s, or the way you had to twist the knobby thing in the middle of the turntable so it could play the other sort of record. Even with two of us insisting that this was how it had been when we were children, she remained skeptical.
Similarly, at the preschool Rachel attended, her classroom had a record player that the teachers used for some of the activities. I once asked the teacher if she explained it to the kids as "This is what an iPod looked like when your parents were your age."
