I am a German living in London. Despite the fact, that we are all Europeans, we all live in the "free Western world", we all learn English in school and I am a communication expert by profession, I wonder if I always understand my fellow Londoners correctly? To be honest, I doubt it. :)
Also, why do people ask me all the time how I am? How do I know if my emails are polite enough? Did I make enough small talk? Which hand signs were cool and which were offensive again? Intercultural communication poses many traps and can easily lead to misunderstandings.
In times of Brexit, I felt it was ever so important to bring out a classic of intercultural communication to help you (and me) really understand the Brits. Enjoy!
