reddy,
i tend to agree with you partly. our society is divided based on race, cast, creed, occupation and so on and there are people who use these various pronouns accordingly...however, i don't think  'hajur' 'baksyos' are only used by people who are directly/indirectly related to feudalistic society. just like 'ta' is popular among close friends of any society..and as i said, it's the tone with which you speak that matters. and again, it has lot to do with our culture as well: being respectful to elders being one of them. it's not feudalism.

i have seen people who call their mom/dad 'timi'...again how you speak with them (tone that is) matters.

"baba eta aau ta ekaichin"
"oie mu*i baaabe, eta aau chhitto"

LOL!
