The city of light and romance is home to people famous for their opinions- their likes and dislikes. But the secret to what makes a Parisian is more than the 75 on their license plate. Parisian Olivier Magny reveals it's a full-time job. To be mistaken for a Parisian, forget about red wine or crème brûlée for lunch. Buy the newspaper Le Monde , fold it, and walk. Then sit at a café and make phone calls. Be sure to order San Pellegrino, not any other kind of fizzy water. Feel free to boldly cross the street whenever the impulse strikes-pedestrian cross-walks are too dangerous. If you take a cruise on the Seine, you will want to stand outside, preferably with your collar popped up. When not taking a p'tit weekend away from the city, toss on a scarf and some sunglasses, go to the market for cherry tomatoes, take a stroll in the Luxembourg Gardens with your old friends, and then make an excuse to leave. To truly be cool in Paris, complain, be on a constant diet, wear black, and above all- follow these rules.
