The story of truth
There are people who see the truth, then there are those who speak the truth. Not all truth seer are truth speaker, and there is a good reason for that.
People don't like truth, they like their own version of reality. So the person who speaks the real version is hated by many, and most of the time truth does more damage than good.
So if you see through other people's shit, try to avoid speaking it, keep that mouth shut.
