It began two weeks ago. J. was to pack char siew rice before mahjong, while I got cakes and coffee. The rule was that the winner would pay for all F&B expenses incurred before, during and after the game. Their eyes lit up when they realised both of us spent $19 each. D. wasted no time in collating 4D bets. We didn’t win that evening, but the obsession stuck. And they reported the presence of 1919 in their daily lives every other day.
