Plz stop spreading lies that Hindi is our national language. Indian constitution never mentions any language as national language.
Every Indian language is unique and every body must accept and appreciate it.
As of Jayaji is concerned she is wrong in mentioning that she would only speak in Hindi. In Rome be a Roman. If she speaks in Marati she would have gained immense respect from people.
These people must learn from superstar Rajinikanh. He speaks in Tamil in Chennai, Telugu in Hyderabad and Kannada in Bangalore. Hence he has immense respect among people in these states.
