Being myself from north India, it was difficult for me to get started in learning Kannada. Learning a new language is certainly not easy, all the more when there is not much practical need of it.
Bangalore, being a cosmopolitan city, is comfortable most of the times with English and sometimes with Hindi as well. At other times you can resort to sign language safely (as I used to do while communicating with my maid). But still I wanted to learn the language - may be as a token of respect to all those Kannadigas who have been a part of my Bangalore life. To be able to talk friendly and warmly with my maid or with those faceless auto-walas or with the lady sitting next to me in bus or with my building's watchman's kids, is what I wanted in general.
