I’m at the gate at Atlanta Airport, trying to read, write, and (possibly) think. CNN is blasting in the background and competing with Norah Jones, whose voice emerges from the p.a. system right behind me. Should I wish to follow the CNN anchorperson’s train of thought–such as it is–I would have a hard time. Every few seconds a special security announcement interrupts the TV to remind us that the current threat level is orange. Beeping trucks pass by, travelers are called urgently to board, and people shout into their cell phones. Not a single person in this crowded lounge is actually watching the TV, but some have books open on their laps. Silence would be delicious.
