bug off!!!!!

I don't like telling everything that happens to me to everyone.. not that I am mysterious, neither do I claim to be and I don't not want to be one!!!
I don't care and that's a fact but this is not what I'm going to talk about.. I have talked about me when it comes to this but let me talk about people when it comes to that issue..
let me start by talking about some things about me and then how people react or act in general..
it's true that I don't like to talk much but that is only at few places or times.. I can be soooo talkative and I can be really quite..
but I don't like to spread things about me everywhere only to the people that care about me but that is kind of impossible having someone around that their mouth can't shut up and if they finished talking about what happened to them then they'll start talking what happened to me... *no offence*
Now, it's their -should I stop saying 'them, they, their?- nature and this is not what I wanted to talk about but no harm in mentioning it.
I don't know why people want to know everything about everyone.. -that is not all people but a lot of them- and some of them, you don't know them well... so it's irritating when they ask about what happened... and you can't just tell them I don't want to say.. although we have tried: it's not going to do you no good if you found out or it's none of your business or why do you want to know,, etc.
Some are just too curious and I can't understand why they are so.. sometimes when they ask me something I just remain silent and sometimes they give up and after some minutes I answer with a tone that is like whatever...
just mind your own business and leave me alone!!!!
