Im sitting in the walled city park, on the outskirts of Hong Kong. Just drinking a beer and playing chess with a local. He does not speak english, i do not speak Cantonese. The game is very close. Then a man sits nearby and starts to play music, just for himself. We onlookers are merely a coincidence. Then a man I can not see, in another part of the park begins to sing with the music. They both end on a halting, heart renching note. Checkmate
