One of our great poets, Discépolo, said once:
tango is a melancholic thought that can be danced….
And when I saw the skeleton at the window,
one of his tangos, titled Cambalache, came to my mind…
A Cambalache is a shop were all kind of used goods can be sold… .. In the middle of the crisis at 30’s, he wrote..

Like in the disrespectful window
of the cambalache
life is mixed up, and wounded
by a rivet less sword
you can see a Bible crying
against a water heater.
Twentieth century, a cambalache
problematic and febril!
If you don't cry you don't get fed
