30 Rock 's fictional character, Liz Lemon asks that very question to her office colleagues when she returns to NYC in episode two of Season Three, 'Believe In The Stars' (she'd met Oprah on a plane while travelling the previous week). Today, I feel the same way. Why? Because five minutes after I got to the Hospitality area of the New York Film Festival following the first screening of Ava DuVernay 's heart-stopping documentary, '13th' , Oprah Winfrey walked into the room. "Hello everybody!" Gracing the four walls of the Alice Tully Hall's Green Room with her spunky presence, Oprah addressed the whole room. Everyone inside it instantly felt grateful for something they couldn't quite pinpoint. Her friends said hello back, while the rest of us did our best to act like staring at wallpaper held the secret to the meaning of life. "Good god, Lemon" I can just hear an invisible Jack Donaghy reverberate into my skull chamber.
