Parmi les français

I've never had a problem living among the French people with their thorny unwritten interpersonal etiquette. I don't, normally, say hi to people I don't know, or smile directly at them.  I always say bonjour to the proprietor when I enter a shop. Nobody told me to behave this way, it just seemed like the thing to do at the time. Anyway, I've never got my feelings hurt by a rude Frenchman.
