Open or closed door policy?

Americans who invite you into their home for the first time will often, in a grand display of pride of home ownership, give you a tour of their place - of course, once more, this does not always hold true, but it's a fairly common practice. This happens only very rarely in France. A French person's home is his or her private space and, as such, it is not to be shown to strangers or friends, unless they are extremely close friends.
