‘life is not fair’. This seems reasonable as a ‘Truth of Life’ to most of us because we know it is ‘true’. If we then say that this is true and we live by it, then we would not get particularly upset or not even get upset at all if something was unfair, because that is how we believe that life works. It doesn’t mean that we don’t try to be fair in life but it does mean that when life is unfair we accept it and deal with it.
