What is “truth”? It is when a person disappointed in life is saying what (s)he is thinking. But for some reason (s)he is always thinking something unpleasant to other people. So it is easy to understand that the filter (s)he strains information through is not “truthful”, but “unpleasant”. It is time to accept the fact that people who tell the truth are psychological sadists enjoying emotional sufferings of those who they say nasty things to.
