it is karunanidhi who spoiled the chance for the students in tamil nadu who were in colleges during 1960s to learn hindi language and now the result is these people in their middle age now feel betroyed and denied an opportunity to learn hindi in tamilnadu,either unable to communicate or travel freely in north or do business in north or go for employment in north.except tamilnadu, people in other states in south know hindi well.karuna daughter,son in laws,nephews have learned hindi now and even karunanidhi learned hindi and talked in one meeting- sudden love now.karuna is an opportunitist politician who work only for the betterment of his family members and did not do anything for tamil people.
