there you dont have to ban, because you generally get old movies only in the theaters..that too very rarely. As i had been in Chennai, it has become very tough for me to survive in the weekends, as i was not knowing to speak tamil. people are not bothered to response/help if i seek for some info in Hindi/English... The same is happening for me. Since my supervisor is from TN, he forces me to learn Tamil. The reason he gives for me to learn tamil is he does not feel comfortable speaking in English. This is my own experience in Bangalore. Dont you think it is rediculous?
