Are you a hindu?
This was the question the guy sitting next to me in the bus asked during a recent trip of mine to kancheepuram. I believe he wanted to know as to what language I speak to make a conversation. So I said "naa tamilzh dhaan" ("I am a tamil guy") realizing the guy was also a tamilian (written all over his face).
The guy first wondered if I was a North Indian, but something made him certain I wasn't a southie *duh*. But the question he threw at me asking for my religion really irritated me. I was hell pissed and was so tempted to ask "why the F*** dyu want to know that?". But then I realized it was probably just a lack of proficiency in expression. Or it it stands testament to how much religion and cast are ingrained in this country.
I'v never asked such a question, and rarely been asked. And I see no reason to. Do you ever ask someone such a question? How do you feel when someone asks such a question?
