Maybe we're all like that with our mothers. They seem ordinary until one day they're extraordinary.

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.

May and I are sisters. We'll always fight, but we'll always make up as well. That's what sisters do: we argue, we point out each other's frailties, mistakes, and bad judgment, we flash the insecurities we've had since childhood, and then we come back together. Until the next time.

Sisters, as you know, also have a unique relationship. This is the person who has known you your entire life, who should love you and stand by you no matter what, and yet it's your sister who knows exactly where to drive the knife to hurt you the most.

I think all women have a friend who at some point dumped them or betrayed them or deeply disappointed them. And at the same time all women have a friend who they dumped or betrayed or hurt in some way. That's universal in women's friendships.

I don't really know anything about the movie business, even though I've lived in Los Angeles my whole life - somehow I've never bumped into it.
