The most important word in the French language

Perhaps the first word you are ever taught in French is BONJOUR. but what they don't tell you is that bonjour isn't just a greeting, it's actually the most important word in the French language and if you use it correctly and frequently it will make life so much more pleasant for you in France.

It's likely to also help change that stereotype ( still active today) you had of impolite French people. 

You can never overdo it with Bonjour, when you think you've said it too much, you're probably saying it just enough.
