At work one morning I'd put Bach's Sixth Brandenburg Concerto—the one without violins—on the sound system. I've always found Bach to pair well with Sunday brunch.

Unfortunately, the disk had a skip in it. The same brief phrase repeated and repeated, playing over and over and over.

As I was crossing the floor to change the disk, the door opened and a customer came in.

When she heard the music, her face lit up. She gave me a radiant smile.

“Oh, I just love Phillip Glass,” she said.
