Strangely enough, right now, at this very moment, I am thinking about the concepts of “believing” and “not believing”. Who don't I believe? I don't see how it could be otherwise. © “And then you ask why I don't tell everything as it is, you don't have to open up to people and tell the whole truth it's not always necessary”. Any lie will become known, no matter how much you hide it... which I don't particularly like to do or know how to do. “Anything you say will be used against you in a court of law” is more about lying. I mean, how can you hurt or be hurt by the truth? Only if you don't want to accept the truth yourself.
The other conversation is that you're not happy with the truth. And this is nothing but an incentive to change yourself for the better. If this truth suits you, then it is the problem of others who are not ready to accept you with it, as well as just you, since you and the truth are one in your eyes.
