&éçà you too!
i think one of the reasons i love being in france and in paris has to do with the way people speak. in general, i have a very foul mouth and will curse at the drop of a hat. my favorite is always fuçk and one of its many forms.
this morning, while shopping with a friend, i waited patiently to go try on the dress i saw yesterday but didn't have in my size. while waiting, all the clerks for the shop were strolling in and out and conversing the entire time. every other word out of their mouth was "fuçk" this and "sh!t" and "whore". granted, they used the french words. as i stood there and listened i started to look around to see the reactions of others. nada. or rien if you prefer.
i smiled and started to nod because we speak the same language.

Potty mouth!
Actually, I'm a potty mouth too though I'm trying to clean it up. Don't want my baby dropping the f-bomb at daycare.
i embrace the potty mouth. we are just going to have to have that talk with the daycare... better they learn it at home than on the streets. ; )
When I picked up my son from school today, he asked where I had parked the car. I indicated a parking lot that was far-ish away. Then I heard the kids giggle, and my daughter said "Daddy would say 'C'est a Trou du Cul-sur-Fion'."
I laughed, and told them, "In English, we'd say 'East Bumfuck'."
Then I was slightly horrified that I'd taught my children that expression. But as you said, better they learn it at home than on the streets.
