I watched the taped match, and John McEnroe said just before a break for commercials, that if they spoke French He would leave.
I knew that Serena could speak some French, because she did so in Montreal, Canada in 2000, after each match and also after retiring vs Martina Hingis in the final.
I noted this on another board, and was told that she did not speak it that well. I was confused because of all the glowing reports form Canada when she addressed the crowd. Seems that Serena's French has a different accent than the French spoken in France, more like the French spoken in Quebec.
Gee, People in Georgia Speak "English" but would NEVER be mistaken for people from England.
While Venus' French was more like the French Speak, She does not know French as well as Serena.
John did not leave as he said he would.
Serena was also reported to have spoken Japanese in Toyko, in 2000, although I don't know if she knows the language or just learned a speech that she would give if she won, which she did.
