Each country has its own language, its own culture and of course the cuisine. We all know at least 1 foreign language that would create at least exams. But will we understand native speakers?
Arriving in a foreign country for themselves is unlikely we will understand something of the vocabulary of the inhabitants of this country. Why? Because these people didn’t have an accent in school, we won’t be able to understand them when they start talking to each other with slang of the language, or maybe just words that we don’t know
