(By a French person) This is going to be basic etiquette and usually untaught but rather important grammar. -if someone says "je n'aime pas la glace, et toi?" (I don't like ice cream, do you?) and you do like ice cream, you don't say "oui, j'aime beaucoup la glace" you say "si, j'aime beaucoup la glace." Si does mean yes in Spanish but in French, it is used to contradict a negative statement. -say you're walking around the streets of Nantes and spy a colleague/friend/neighbor. You should shoot them a "bonjour," no? However, if you see them again that day, don't say bonjour again. People may take it as offensive as though you've forgotten about your previous meeting! If they know you're a foreigner, though, they probably won't take as much offense -tip the waiters; being a waiter or waitress in France is a highly respected and desired job requiring expertise in foods and which wines go with them! -if you're eating at someone's house, definitely compliment the food, they'll adore it! -just to clarify, it's usually not okay to scarf down your food at a restaurant, but if you're eating a crêpé while walking down the street, chow down!! Also take advantage of the crêperies everything is amazing there. I recommend the lemon sugar, but there's a billion types of crêpes! -speaking English is fine there, most people know enough, if not a lot. -if you bring a dog on a walk, pick up its doggie doo doo. It's such a huge problem (especially in Paris) and there's a hefty fine if you're caught leaving their poop on the ground. -MANNERS. Remember your "s'il vous plaît" and "merci"! -sometimes restaurants are called "restos" -snails are a delicacy do not say "eww" if you see someone eating escargot or see it on the menu -don't spend all your time in Paris there are other cities in France without nearly as many tourists. -have fun, my home country is gorgeous and we aren't assholes. People who stereotype the French just want to fuck the entire Eiffel Tower.
