Being inquisitive - is it right always?

Had a very hectic day arranging a get together at my place...shopping, cleaning, cooking, etc...

Finally my mood is upset by some unwanted personal questions asked by some unwanted people...why should i be upset by such people who have no role in my life is my first question...but i still get really irritated with such people...i cudnt help myself in this regard so far...i am trying really hard though....i wish i succeed in this some day.....

i literally get mad at people who intrude in other's personal lives when they dont want to reveal anything about their lives....even if one is an open book....i feel it is unnecessary to poke into other's personal lives....i hate such nosy people since childhood....i myself dont ask any personal questions even to my closest of friends though it is not wrong to do so...but strangers..they have no right to poke into others personal lives....if i talk with a stranger or someone who is not my friend, i think 100 times before asking a question to them....do i really need the answer from that person.....i dont understand why everyone dont realise this..even i have equal opportunity to embarrass or irritate anyone....if i asked the same question back, what would they answer.....i never had the courage to be so rude though.....i dont want to bo so...but i wish people learn not to interfere too much in others lives....
