Why should I learn a language - Post Brexit?

You may think that I became a language lover when I married a man with a different nationality to me. The truth is my favourite subjects to study at school were always English language and foreign languages. I was fascinated by travel and being able to communicate. After a school trip to Rouen where myself and some other students were insulted in English by German school children (Yes they insulted us in our own language which they could speak pretty well!) I knew I could not cope with only knowing my own language.
