When it comes to your "secret thought life," what are the differences between your inner and outer persona?

I’m not really a nice guy, but I play one on t.v. If my closest friends and family members knew the intricate details of my secret thought life, they might be a little shocked. I protect my secret thoughts; they’re hidden deep below the line of being completely known. The reason why I don’t share them is because, due to the way my brain is wired (I have bipolar), I tend to have 3–4 complete thoughts randomly running simultaneously. I choose the ones that present my persona as nice, kind, etc. etc, and I exercise wisdom whenever possible. Some of my thoughts, though, are rather explicit and nasty.

What about you and your secret thought life? Do you edit more often than not?
