I set the water on my stove to boil and flicked on the kitchen radio, which was, as usual, set to NPR. The announcer was giving an update on the ebola crisis, now listing fatalities from a recent accident, now discussing the stock market—I changed the channel. I’d had a long enough day already and had no desire to sit and listen to the ongoing string of bad news. I flipped through channels until I hit a pop station that wasn’t in the middle of a commercial break. As I pulled out plates and pasta sauce, a new song played in the background.
