I used to talk to people I considered good "friends" who I felt very comfortable around and didn't feel the need to watch what I was saying, one person in particular claimed to be a pretty liberal-type person, worked and lived in a very liberal area, but they would often make racist/sexist jokes to me and I would go along with it, not really realizing how much I was suppressing my own personality and what I knew was right deep down (which was to not be racist/sexist etc) in order to maintain that comfort level in our relationship. I wouldn't want the NSA releasing older texts I sent to various people I knew, if you know everything is being watched and recorded then you really need to act the way you want to be perceived by the whole world now, because there is no private/public persona anymore, just you and how you want to be all the time. I knew that one person for decades and they ultimately became basically a nemesis, have to be careful of everyone
