I am a very curious person naturally but over the years I've tried to keep my curiosity to the barest minimum so i won't end up like the proverbial cat who was killed as a result of curiosity.
Personally, i appreciate not been told some certain secrets especially those i am not prepared to hear of or know. It in a way shield me from certain unpleasant situations but nevertheless it becomes painful if i have to find out myself and i might never forgive the person.
The bottom line is keeping secrets to protect me is something i very much appreciate but you've got to go the extra mile of making sure i did not get to find out by any other means.
