http://en.wikipedia.org/wiki/National_language
Many times people asked me "Can't you speak in Hindi, as it is our national language ?". I heard this even from educated group. India has no national language. Hindi/English is in use only for official purpose. They are not declared anywhere as our National Language. This clearly proves that everyone wants to have their likes and dislike to get reflected in Indian constitution, but that will never happen. All languages originated in our country has equal value and respect.
If someone ask the same question again in future, I will politely educate them.
Jai Hind and வாழ்க தமிழ்.
