I am 61 and retired. I have been unfaithful once in 1984 for a brief encounter but carried on a six year "relationship" with a dirtbag that ended on discovery three months ago. I have been an addictive personality all my adult life and a narcissist with a huge ego, though at heart I am a good person.

I could be wrong.

Now, can you answer my question about white lies in social interactions?

No, I will not.
It is a detour away from your self examination.
