Driving in Paris? One must be a masochist.
Yes, a few Parisians can be rude. Oh, let's be honest, they are down right nasty. Don't let these rotten pommes ruin what could be a most memorable weekend. Most of Parisians are a friendly lot and are eager to help tourists with directions and recommendations. Saying "bonjour," "s'il vous plaît," "merci," and "pardon." Be liberal with saying "monsieur," "madame," and "mademoiselle."
Definitely try some treats at a bakery. Here's a famous one:

Finally, a performance at the Opéra National de Paris, Palias Garnier could make for a spectacular evening. And it's quite reasonable. This weekend, they are performing a ballet commissioned especially for the Paris Opera and is having its world première this weekend.
