Talking to someone, when both your native languages are not the same, can sometimes land you in a sticky situation — where emphasis in words could be interpreted as offensive or aggressive.
Naturally the instinctive reaction is to be offended and respond in kind, often with a rhetorical question.
Take a step back. Absorb the possible meanings. Consider a thoughtful reaction.
Then, like Switzerland, be neutral.
You may find their tone aggressive or offensive because that’s what your language teaches you, whereas it could just be a passionate one, like their language teaches them.
