• Lauren Graham and Peter Krause waiting in line at Furin’s sandwich shop in Georgetown on Wednesday — she in black pants and tall black leather boots, he in a blue chambray shirt, untucked and sleeves rolled, sports coat under his arm. The “Parenthood” co-stars and sweethearts took their Thai chicken salad and curried tuna-on-rye to a window-side table they shared with a handsome older man. . . Google, Google, yes! . . . her dad, Larry Graham, president of the National Confectioners Association.
