My ex front door in my old flat has been filmed, fleetingly, on the French version of Come Dîne With Me as the historic building above the cheesemongers, and there is a TV series being filmed right now on location in my town depicting us all as mafia connected murderous types but in a tasteful and sort of Inspector Morse way, obviously. I live in Corsica.
I absolutely cringe whenever there is a depiction of where I live or have lived on the old telly screen and just want to shout, "Oh God, no! We're not all like that!"
Apart from the hand over mouth, mumble mumble well, sort of kind of like but...
Do you have experience of this phenomenon?
