Recently in Slate:

“One recent study conducted by officials at the Paris Metro — which looked at ‘missed connection’ ads placed by urbanites looking for love in the city — found that the Metro ‘is without doubt the foremost producer of urban tales about falling in love.’ The seats closest to the door, it seemed, offered the best opportunities for falling in love with the proper stranger. ‘The Metro is not the emotional desert, the social vacuum, that we sometimes believe it to be,’ observed the chief of the Paris Metro.”

Of course, that’s Paris. The sewer is romantic in Paris. But it couldn’t hurt to sit near the door, just in case. (Right, Dixie?)
