This reminded me of a video I saw once, many years ago. It was told by the last speaker of a language - from a tribe in El Salvador, iirc (Central America, for sure). Most of his tribe had been wiped out during civil war. He and his parents were the last living speakers of their language. When his parents died, he was the last. The video was a long, tearful poem, telling the story of his people and their destruction. Of course, no one could understand a word of it but him, but the emotion was unmistakable.
