One Wednesday night in January, George and Lara Moynihan, both 39, were watching Modern Family on their TiVo when the doorbell rang. George, a plastic surgeon, went to the door and greeted the man who maintains their neighbor's often empty Kenwood home. He was accompanied by a Secret Service agent. "The president is coming by to say hello," the agent said. "It's going to be in about 30 minutes."
"Who was that?" Lara asked when George returned to the living room. "The president is coming," he said, shrugging. "In 30 minutes."
