“What are they doing?” That was the question an older woman, probably around 70 or so, asked me yesterday. She was pointing to a group of 18-ish boys and girls near a YMCA, the biggest (and, so far, only) Pokestop in the city where I live. Without exception, the teens were all staring at their smartphones. “They’re playing Pokémon Go,” I replied. The lady didn’t comment, but her facial expression was a mix of disconcert and skepticism.
