The French never let a crisis spoil a weekend — as you can tell. As the working week draws to a close in a cafe off the Champs-Elysee in Paris, there's a mood of keen anticipation. The wine's flowing with extra velocity. The French are preparing for two days of sports, food and family fun. They seem unperturbed by, or perhaps unaware of, the fact that their fate depends on what happens this weekend and the days that follow. If things go wrong, life won't be much fun any more.
