The best way is to answer a question by a question…
Question: “Aapki salary kitni hai??”
Answer: Why do you want to know?
…Its a decent way of letting people know, I’m not interested to answer your question.
I’ve been asked these questions back home…What time do you sleep, when do you wake up, where you shop, where do you buy your clothes from…
Most of the times relatives just want to know your lifestyle in the west…
and sometimes its about status.
Status is something like this …“When you buy things you dont need; with the money you dont have; to impress people you dont like”. If you remember this definition, you wont feel that bad, when someone is asking you these questions.
