The only time my vocabulary increased, IMMENSELY after I had finished my apprenticeship was when I worked at a girls boarding school. 800 girls from all corners of the world, mainly service personnel kids but, my God, we knew the swear words were not a foreign language?https://twitter.com/C7RKY/status/1019520004033826816 …
Haha! I understand what you mean. As a teen I travelled around Europe on football tours once upon a time and we always made a point of learning a few words of the local language. Yes, no, please, thank you, beer, all the swear words... that sort of thing. ;-)
