Why is India a unique country?

The nodding of the head in India is a sign of a “Yes” or a “No.” But how the head is nodded differs in different parts of the country. You have to be a local to understand the secret language of head wobbling. So, during your travels, while you might think that the nodding was a “Yes,” in reality, the person might be saying “No,” therefore it is advisable that you get a verbal answer and not just rely on the non-verbal signal.
