Lulu Miller, reporter at NPR and former Radiolab producer, tells us the story of how her entire world view flipped in one scary moment. It happened on a bike trip she took with her friend Soo. Lulu and Soo are, well … different. Lulu tends to be an optimist who sees the best in people, while Soo has always been a bit more of a pessimist about her fellow man. Not surprisingly, a bike trip across the country turned that charming difference into a friendship on the rocks. But then, an unexpected encounter in the wilds of Virginia left Lulu and Soo deeply confused about the right way to greet an imperfect world.
