“This is what you do on your very first day in Paris. You get yourself, not a drizzle, but some honest-to-goodness rain, and you find yourself someone really nice and drive her through the Bois de Boulogne in a taxi. The rain’s very important. That’s when Paris smells its sweetest. It’s the damp chestnut trees.” – I can almost hear Audrey Hepburn saying those words in her 1954 film Sabrina.
