The Role of a Culture
Culture plays a much bigger role in our lives than we think.
A great deal of context can be lost when you cross the boundaries of one nation. Many nuances can be missed or overlooked if you’re not a native speaker or if you don’t understand the current lingual context of a country.
The best you can do is to be open, forgiving, and inclusive as possible. And if someone misses an important clue, perhaps you can first try educating and enlightening them before assuming they did it deliberately.
