So I heard bells. Ka-ling, ka-ling, ka-ling. Not Christmas-y sleigh bells, not church bells, not jingle bells, not wind chimes, resonant, melodious, substantial bells. They sounded too leisurely to be some kind of alarm. I poked my head out the door, and there was the man who teaches the "Inquiring Minds" class striding down the sixth floor hallway waving a set of three or four metal bells ranging in size from coffee-cup-size to pint-size on a leather harness. "Camel bells," he said with a grin. "It's how we announce the monthly floor meeting." He taught in the Middle East before he retired, so they're probably genuine. And they sound very nice. So once a month, I will get to hear camel bells. I wonder whether he might share the pleasure of walking them down the hall.
