My father has asked me to be the fourth corner at the Joy Luck Club. I am to replace my mother, whose seat at the mah jong table has been empty since she died two months ago. My father thinks she was killed by her own thoughts.

"She had a new idea inside her head," said my father. "But before it could come out of her mouth, the thought grew too big and burst. It must have been a very bad idea."

The doctor said she died of a cerebral aneurysm. And her friends at the Joy Luck Club said she died just like a rabbit: quickly and with unfinished business left behind. My mother was supposed to host the next meeting of the Joy Luck Club.

The week before she died, she called me, full of pride, full of life: "Auntie Lin cooked red bean soup for Joy Luck. I'm going to cook black sesame-seed soup."

"Don't show off," I said.

"It's not showoff." She said the two soups were almost the same, chabudwo. Or maybe she said butong, not the same thing at all. It was one of those Chinese expressions that means the better half of mixed intentions. I can never remember things I didn't understand in the first place.

My mother started the San Francisco version of the Joy Luck Club in 1949, two years before I was born. This was the year my mother and father left China with one stiff leather trunk filled only with fancy silk dresses. There was no time to pack anything else, my mother had explained to my father after they boarded the boat. Still his hands swam frantically between the slippery silks, looking for his cotton shirts and wool pants.
