Thanks to our latin origins, we, Parisian and French people in general, think that rules are made to get round.
My son and his mates, as well as many children at the public parc, use to do as if they haven't noticed the interdiction.
Mon fils et ses copains , ainsi que plusierus autres enfants au parc ont l'habitude de faire comme s'ils n'avaient pas remarqué le panneau d'interdiction.
It's almost written on every public buildings
So when we're Parisian, since for many and non legitimate reasons ; ) according me, we're not appreciated, we probably don't tell anyone that we are from the Capitale..
