When the truth is painful, we are not willing to accept it. Truth becomes painful when it is not what we expected to be or that our desire, hope or expectation is contradicted by facts. Unwilling to accept the truth is "denial." It is not hate; it is unwanted or unwelcome truth. the sooner we learn to accept the truth, the sooner we find peace within and move on.
