Some people are unable to grasp the concept of privacy and tact, therefore, when you tell them they are being nosey, they cannot understand. Basically, they have no idea why what they have asked could be construed as being nosey.
Maybe they are so completely unaware of how their actions are perceived by others, that they just don't see themselves as such.
Because they just can't quite believe , that they could have a flaw of their own, so u have to explain any criticize u give to them, and then realize u just wasted ur breath, because they'll never understand ! ..
Probably because "nicely and politely" really doesn't have anything to do with getting ones point across. This is why people who try to be nice and polite always wind up breaking down into something that isn't so nice and polite.
They are ignorant and think they have some right to ask a question and receive the answer.
EITHER THEY DON'T SPEAK ENGLISH VERY WELL, OR THEY'RE BEING ANBNOXIOUS
When I say it they don't ask...It goes something like this...
I look at em and say WTF....They get the point...
