Don't worry. She won't now that her big sis has pulled out. It's nothin but a consipiracy I believe.
They will never play the same tournament except the grand slams, lipton and the year end championships. I won't change my mind until they start playing the same event constantly. I don't really look at them as two distinctively separate players. I'd rather see them as "team Williams" which don't compete against one another. It's like Sumo which doesn't make wrestlers from the same camp face each other. In tennis they still have to but they can't be as competitive as when they face other players. So it's simply the same case as Sumo.
