After what Caroline said about the grunting issue today it made me wonder. It seems like those comments were targeted at Azarenka and Sharapova. Of course, Azarenka says she will not stop. Stosur said that it doesn't bother her on court, but that it sounds terrible on TV.
They've been tweeting back and forth a while ago and recently practiced together in Monaco. Friends can have different opinions on stuff, you know?
By the way, Caro's twitter activity is probably the last thing to judge anything that's going on with her, she has recently gotten pretty lazy with tweeting, often there's nothing for several days in a row. Not everyone puts everything they do on Twitter
if they are no longer friends because of something caroline said about grunting then it wasnt a very strong freindship in the first place. caroline would probably be better off without a friend who would dump her for that anyway
however my guess is vika isnt that sensitive and they still are
