Afew years ago, I was out on a run with a friend in New York. It was the first perfect day of the year—60 degrees, partly cloudy. The city seemed new again. As we jogged through the West Village, she suddenly came to a stop in front of a store window. “Let’s go in!” she said. I was baffled. But we’re in the middle of the run, I thought. How could we possibly interrupt this?
