It IS the 21st Century... Women can be more independent nowadays with technology and communication improving rapidly. I never even gave it much thought to the absense of Pierre-Yves. There are times when couples can do without each other, y'know. I'd feel suffocated if my boyfriend followed me everywhere and even more if he felt insecure towards my success. What kind of a man would he be?? I'm sure Pierre-Yves is not insecure about Justine's success though; there's no reason for it.
BTW, I do NOT want John McEnroe commentating. Anyone but him, please!!! I would like punch that man in the face every time he tries to open his mouth.
