George W. Bush, famous for shunning the social whirl and retiring early most nights during his years in the White House, was back in town last week for a two-day world health summit, put on by his eponymous policy institute. He made it to a Tuesday night dinner party for participants at the Washington home of longtime supporters Wayne and Lea Berman, his former social secretary.

But at 8:45, he stood to address the room. “Nothing’s changed,” he announced. “It’s bedtime. Goodnight.” Haha! Well, sort of a joke, sort of not: He did stick around to say a few words, but indeed, didn’t linger much longer.
