True confession: I am probably the worst person on the planet at spotting celebs, especially here at Sundance where everyone is wearing furry hats and enormous sunglasses. But I do love people-watching, and one of my favorite parts of people watching at airports is reunions. Like just now, there was a crowd of people with yellow smiley-face balloons and "welcome home" signs waiting in front of me, and then a guy dashed down the escalator, swept up a little girl (his daughter? younger sister?) and burst into tears as he embraced his family. It could have been a movie moment. Don't know who he is, or where he's been --he's not a famous face to anyone but the people here to greet him, but he was awful glad to be home. That kind of real human drama is as good as spotting a celeb.
