Hiding the truth, is never the answer. Lying for someone is never the answer. You can't lie to those you love and expect them to understand your self absorbed reasons why. It doesn't work that way. Dishonesty is a deliberate orchestrated choice - a decision to act or speak without regard to those involved.
If there is one thing I have learned in life, it is not to enable a liar. Doing so only allows his deceit to grow.
