It’s a summer afternoon at one of our country’s most popular malls, the Easton Town Center in Columbus, Ohio, and teens are doing what they’ve done for decades: roaming around in groups of twos and threes, browsing and gossiping and passing the time. Near the center of the complex is a renovated Abercrombie & Fitch store, brightly lit and covered in wood panels. Two teenage girls stop to review a wall of flouncy cotton-poly knee-length floral dresses.
