My brother was a middle level state government officer in 1968. DMK came to power in the state just a year before and everyone was thinking that Tamil would be used in all government offices (almost four decades later that is yet to happen fully). One day my brother had a meeting with the district collector. He greeted the collector by saying "vanakkam" (greetings in Tamil). The collector, a non-Tamil from another state, was surprised and asked my brother, "Are you DMK?" My brother said, "no sir". Even today, four decades later, most government officials greet each other with "Good Morning" and not "vanakkam".
Thanks for sharing...
