Seeing the map took me back to the sweetness of living in a country where an exchange of kisses is an intrinsic part of every meeting.
In my 18 months in France, I quickly learned cheek kisses are expected not only by friends, but neighbours, colleagues, landlords, teachers, and even doctors greeting patients in the waiting room.
Failure to comply can make you persona non grata - case in point being the mother at my children's school who would hold out her cheek and haughtily demand "bisous" (kisses, note, in plural) if we forgot.
The kids also kissed each other as they entered the classroom, and really, there is no sweeter sight than a bunch of otherwise rough-and-tumble boys giving each other gentle pecks to say hello.
The same can be said of the men, who in our region were rough, silent farming types.
The cheek kiss - though very different from a proper French kiss - is a beautiful, intimate ritual. It is a soft, humanising gesture, and one of many things I miss about France.
