If I didn't want someone to ask something personal about me, they wouldn't have any information to ask the question
I have to agree with this!!!
Information is power...
There are those people that I and DH have learned to just keep silent, and don't let them in on anything.
Sometimes, the information is a little more obvious and widely known. So, it is not like it is a big private secret.
Sometimes the person(s) who are on a need-to-know basis just can't or WON'T keep their mouths shut.
But, other than those kinds of situations, I SO very much agree.
If one is heard/overheard saying... "I am going into hospital (was in the hospital) for 4 days..." then, it becomes Open-Season!!!!
If it were to happen that, even after my best efforts, the wrong persons were asking such personal questions, I would have no problem letting them know, very simply and directly, but in a non-confrontational way... "I feel like that is just my own personal business...." Lather, rinse, repeat.
Sometimes the semantics can make a difference.
If one uses the word "YOU", or "YOUR" instead of 'I'.... As in "Why would you need to know???" Then that is continuing to involve them and engage them... It would also very likely be seen as stand-offish at the least, and confrontational at the worst.
