“We hug, but there are no tears. For every awful thing that's been said and done, she is my sister. Parents die, daughters grow up and marry out, but sisters are for life. She is the only person left in the world who shares my memories of our childhood, our parents, our Shanghai, our struggles, our sorrows, and, yes, even our moments of happiness and triumph. My sister is the one person who truly knows me, as I know her. The last thing May says to me is 'When our hair is white, we'll still have our sister love.”
