Cultural Differences

You know how sometimes when someone says a word that can be considered dirty and you giggle?

I wonder if French people giggle at Americans because we say "Dur..." (duh).

Dur = hard in French.

I would giggle if I overheard a tourist say "Uh.. hard!"

On another note: French doesn't have a word for 'gender' the way we use it here. They just use sex for both the social and biological aspects of gender/sex. It's very limiting for non-heteronormative people. But I suppose if a need arises for a new definition, it will be created. Like gender was in English.
