Working in Paris many years ago, one of my colleagues was a Breton. Great bloke and we had bizarre and often hilarious conversations in franglais.
And of course we had a few drinks in the Irish pub now and then. They had a map on the wall with Scotland, Ireland, Wales, Brittany and Galicia shaded in green.
One evening he pointed to the map on the wall and said “pourquoi?”
So I said “La Bretagne est une terre celtique, nous sommes frères celtes, nous avons le même sang!” (well, all right a semi-inebriated franglais version of it)
Should we have another Guinness?
He must have lived in Paris too long and was obviously unaware of his heritage.
And as a Celtic country they produce great music, of course
