Dos: - wave your hands when you talk, just be like an octopus
-slap the ass of you bro (in a friendly way , so no slow sexy strokes) , "no homo"is not needed
-Talk as loud as you can, expecially when you're phoning somebody, you want to make the people close to you deaf, so they won't hear politicians' bullshit anymore
Don'ts: -You're french, so i trust you have a better commonsense regarding food than the average tourist. Regardless, i feel like i have to say that: DO NOT ask for: ketchup on pasta or pizza, No pineapple Pizza (pineapple + tomato sauce = terrible idea), basically raping italian culture with improper ketchup use is forbidden
-Do not do strange stuff with monuments, you risk to damage them (again cultural rape is forbidden)
-Do not pretend to be a fascist, that's downright dumb, french military in WW II was better than Italy's
