There are some idiots in this world who never walk out of their home and shit such words on twitter or social media creating unnecessary rift between other people. Such rascals can never dare to go out of their house but because of such arse comments, they make life of many other difficult who are living far from their houses in another states.
I have been in Chennai and people there are moderate. They try to speak to us in as much hindi or english they know. Its unfortunate that we can't interact with them in their regional language but to take help and show gratitude from each other, we never need a language. Gestures are enough.
