Disclaimer: I am grossly generalising here and I know that each of you can think of thousands of examples countering what I am about to say! Also, thanks to The Girl for the idea.
Chennai, culturally, can be divided into two - the two sides of Mount road. The Tenampet/Poes Garden/Besant Nagar etc.. side(lets call them side A), which are more westernized than the Nungambakkam/Egmore/T Nagar/Kilpauk side(lets call them side B).
A person from side A would probably take life more casually and adopt a "life life one day at a time" attitude. They would be more open to casual relationships, pre-marital sex and the works. They are way more likely to take an arts/humanties course in college and adopt a variety of hobbies which potray that. They are more westenised in their way of dressing and thinking.
A person from side B on the other hand are way serious about their life and career choices. They stick to traditional choices such as engineering or science. They prefer long term relationships and dress more conservately (except for the oh-so-occasional night of clubbing). They derive more fun out of hanging out with small groups of friends or being along rather than wild large parties.
Which isn't weird at all when you thing about it. I know it's still just one city but the people of side A probably schooled together, just like side B did. And if you see the friends you grew up with doing something, you think it's okay for you to do it too and it becomes who you are, if you get my drift.
Anyway, it was just a thought and
Ess said I should post it, so I am. He also pointed out that people in Kilpauk quite make up for the presence of a certain hospital by being super-serious and thinking many-a-time before they make any decisions - whether it be which college they attend or how much money they spend this weekend. I thought about it and realised that, weirdly, it isn't about schools anymore, because all my friends in school who weren't flighty weren't from Kilpauk!
Weirdness.
But, remember, both side A and side B worship thalaivar.
P.S: For those who do not know me or are not from the city and are curious about this fact, I'm from side B.
