acting like babies? i wonder what martina would do if she had sister in the top ten.
i think you should keep your judgements to yourself. why dont you ask the other players who play against their siblings how it is? Then ask the ones where both are in the top ten, not many of those around.
venus and serena can do what they want in their careers. players pick their own schedule. I dont hear anyone griping about what tourneys the other players pick.
