There is one word that cannot be translated to any languages that only appears in the french language, the french use it to express a feeling of discontentement. The word is 'HOOnnnnn Olala'.
When travelling to France, it is important to abide by strict rules of politeness. You should make sure to put in some of these words into your sentences:
So for example, if you want to ask to a french person: 'Where is the bus station?' you should say: 'Bonjour, excuser-moi, merci, pardon madamme ou est la Gare s'il vous plait?'. Which translates to 'Hello, excuze me, thank you, sorry, Miss where is the bus station please?'.
To say 'Thank you' you would respond by 'Ah Merci. Merci beaucoup. Merci a vous! Au revoir Madame! Bonne journee!'. Which literrarly translates to 'O! Thank you! Thank you very much! Thank you to you! See you later Mam! Have a nice day!'.
There will be times where you will find yourself in a delicate situation. Here is a demontration. 'Bonjour! Ou es la gare s'il vous plait?'. You could end up with an answer such as: 'Ah oui la gare, c'est tres simple....'. In this case you just answer: 'Merci!'. And you ask the question to someone else ;-)
You should know, that a french 'Bonjour' is always companied by the two cheek air kiss. Here is a demonstration.
'O! Bonjour Veronique!'/'Salut Sarah! Comment ca va?' kiss+kiss.
