Recently I noticed that non-chennai tamilians and people from outskirts of chennai like me, address another tamilian with a relation (murai vechu koopdardhu)..I mean, when I meet a fellow tamilian girl or a guy, I call them as akka, anna, thambi, maami, maama, ayya etc. I feel more connected with them when I address in any of these forms. The core chennaiites don't address them with any form of relation. They find that there is no necessity and don't try to connect with the other person with a relation. Also, I was noticing that I always have a defined relation to most of the people right from day 1. Unlike core-chennaites, once I find somebody elder to me, they are akka to me irrepective of how frequently I talk to them or how much I am friends with them. And it is hard for me to create and put this person in a category of general pool of friends, unless they are of my age.
