My great-grandfather was an explorer, an occupation prevalent when one had more to explore. On the the archipelago of Tierra del Fuego, he learned to speak Haush, a language near extinction since the 1920s. He taught the language to his son, who passed it on to my father. While we played catch on the front lawn, my father taught it to me, a word relayed with each pitch, returned with each throw.

Three generations dead, I exited the train at Buenos Aires.
