How to Act Parisian
By playing this game, you can learn many of the expressions and gestures that might confuse you when living or working in Paris. My personal favorite is the Gallic shrug--and when combined with the little "pfft" of air that escapes the lips, you'll really be a pro! (When I finally mastered this one, I was accepted all over the city of light. No lie.)
This game is done by the tourist board in Paris, so it's about as legit is they get. Have fun!
