there is only one global language
The French would disagree, strongly.
While i " master " a few languages, i will say i prefer if we meet on neutral ground with the English language.
For instance in the 90ties when i fished a lot, i also ran into a lot of German anglers, them wanting me to tell how come i get fish and they dont.
And i just HATE speaking German with Germans, for one reason, my brain outpace my actual language skill and unlike English i am not really able to think in German, a thing that dont really happen for me with the English language CUZ i often think in English to give my brain a pause from the insanity that is Danish / Denmark.
Also many Germans coming here, they are quite used to Danes speaking German, and it is also taught in school, but really it is mainly along the west coast of Jutland you have a 100 % success with German, the rest of the country getting Danes to speak German are much harder.
Another thing i have noticed, when i was in school about 90 % of all girls in any class would take French language in the 10 grade, but today most girls are clueless to French, i know cuz for instance every year during the Tour de France, like my baker will put up french flags.
So i go " tres bien " and talk French to the girls, and they just do not get it.
So most often i have to translate for the Belle filles working there, and they get a little color in the cheeks, CUZ if its one thing i know in many languages it is how to compliment a pretty girl.
One big problem with that today.
It seem complimenting a girl today is the same as wanting to get into her knickers, but that is not a place i would go, and for sure not with a girl 30 - 40 years younger than me, that would be nasty, and probably also dangerous for my old " ticker "
