I always thought of the "sisters" as the two cities themselves.... Los Angeles and San Francisco. Two distinctly different yet equally attractive places for differing reasons, but both places where one could find adventure (and trouble) easily... so fine, so young (both are relatively young cities in terms of cultural significance)... "tell me I'm the only one" could be thought of as the rivalry between the two places.
