Uncomfortable silences

I am a very open person (duh) - I talk about everything and I share everything without hesitation.  I don't see the point of secrets, I don't enjoy being told classified information and I hate the faux apprehension of others coveting a secret who then gleefully spill the details in hushed tones.  I hate it all.   I hate having to pretend I don't know things, I hate when things are mistakenly revealed in the wrong company and I hate the awkward farcical cover-up and the insincerity that it heightens.  It is so much easier to be honest - like a 4 year old - who just says it all - as s/he sees it.  At some point we all grow up and become dishonest.  I don't get it.
