I was taking soup to the orphans, as usual, when a young man I’d never before met seized me by the arm. “Donald,” he said. “My name is Barack Obama, although that’s not important right now.

“Wi-Fi is available on this flight,” the flight attendant announced on a recent trip I took from New York City to St. Louis. She recited her routine by rote, and Wi-Fi is among the details that now need to be conveyed, along with explaining how to use a seatbelt and enjoining passengers not to smoke e-cigarettes on board.
