The moment you hear the phrase caste feeling you would not be surprised because it is something which is quite common in cine circuit but just that it is not spoken in the open. However, we are not talking about the usually negative shade of caste feeling.
Recently the ravishingly beautiful Radhika Apte got to share her thoughts regarding her experience with the movie Kabali and her interaction with Style Samrat Rajnikanth. The pretty lady was floored with the whole experience and the royal treatment she got.
But here is the inference to caste feeling. Normally, when two Telugu people meet in another state or country they get that feeling. Similarly, when Radhika was interacting with Rajini, they spoke Marathi as both are Marathis. That should be an even more personally satisfying thing for Radhika.
