Puerta del Sol XIV, 2 is coming soon to a letterbox near you. It includes this:

"Los Picapiedra was the Spanish name for the 1960s cartoon family The Flintstones, which, among other firsts, was the earliest animated show to show two people of the opposite sex sleeping in the same bed."

It also includes the observation that the surname "Edwards" must surely be one of the least effortful surnames to type on a QWERTY keyboard. I'm not sure whether anyone's ever pointed this out before.

But PdS XIV, 2 also includes this beautiful definition of tango by Horacio Salas, from his book Tango para principiantes, where he answers the question: “¿Qué es el tango?” with the following passage:

“Una música. Un baile. Un tipo de canción. Una forma de ver el mundo. Una filosofía. Un sentimiento. Una sensibilidad. Una emoción. Una dimensión mítica de la realidad. La nostalgia. El abandono. La separación de los amantes. La tristeza por el amor perdido. El mundo indiferente al dolor ajeno. La poesía de los barrios. El culto de la amistad. El correlato de la historia social del Río de la Plata … todo eso y mucho más: una seña de identidad de lo argentino.”

The Flintstones, QWERTY and tango as the cult of friendship. Where else but in PdS?
