It’s the smell of a walk through Old Havana in the evening, from the Hotel Sevilla to the Cancion del Tango for a dance lesson with Ketty and Felix. Wafts of coffee and tobacco, sweet, sugary desserts cooked with baskets of oranges and mangoes. The scent of peaches beginning to turn overripe, and citrus peel going squishy in the gutter. From a dark doorway a handsome man in white whispers, “Do you want a Cuban boyfriend?” and I speed up a little, squeaking “No! Thank you very much for asking all the same!" And then the old Cubanos at the tango club greet us with smiles, songs, rum and kisses.
