Best of Boston

Celtics center Al Horford has plenty of fans, but it’s hard to think of a more entertaining booster than the five-time NBA All-Star’s younger sister, Anna. Her sharp, take-no-prisoners Twitter feed offers a buffet of highlight reels, detailed thoughts on team strategy, and, most important, a bone-deep optimism that the Celts can still come back and win when they’re down. When they don’t? She’s an amusing commiserator. “Disappointed, but life goes on,” she lamented after the C’s season-ending loss to the Miami Heat. “Gonna go get stoned.” Besides, where else can you get a grainy gif of college-age Al Horford doing a shoulder shimmy?
