I've told very few people (5) -2 with a relative with BP 1 guessed on their own. It's probably irrational thinking but part of me is afraid that if I tell more people (especially people I don't know very well) it will look like I'm either 'showing off' somehow (BP is a bit of a dx du jour) or that I'm expecting pity or some sort of accommodations. On the other hand, I'm afraid so many people wouldn't understand what the heck it means (though may think they do) and I can't be bothered to educate (except those very close to me).

None of this is very rational, but they are reasons why I tend to keep it to myself. Truth be told, I'm a bit ashamed as well...
