Never tell the truth when you can lie. It's so much more creative, and entertaining too.
And it exercises your memory, keeping track of what you said yesterday and last week.
But if you must tell the truth....
This truth smacks of hanging someone else's dirty laundry out to dry.
A long time ago I was sitting and sipping on a brandy with a friend at a bar in a little cowtown out in the wild wild west.
The lady tending bar was a Paiute with three or four kids to feed and a husband long gone.
Down at the end of the bar sat five or six Paiutes. A couple of them were playing liar's dice. My friend and I paid them no attention, but of a sudden the decibel level down at the end of the bar increased exponentially. There was an argument going on.
Just before this, the old man who owned the bar came in and relieved the lady bartender. She sat down way at the end of the bar with her friends.
The argument escalated, and was at the point of passing from the realm of words to fists. The old man pulled a cut-off pool cue from under the bar, cocked it and told one young man to leave. He didn't see why he should leave.
Being a good Samaritan, young and full of wild oats and other things, I stepped over to the young man and convinced him to leave. I took him out on the sidewalk and pointed him toward the other bar in town.
As I stepped back into the bar, I heard the old man in the process of firing his bartender. Being a good Samaritan, young and full of wild oats and other things, I informed the boss man that he had neither cause nor right to fire the young lady. He was already angry and I didn't help matters. I told him that if he wanted to pull a pool cue on someone, he should try me. Wild oats.
The next thing I saw was a .45 revolver in his hand. The business end looked something like the Holland Tunnel. I thought to myself, "All he has to do is move his finger and...."
That was the last time I ever butted into someone else's affair. It just ain't smart.
Unless there is some compelling reason to tell the truth about someone else, and unless that truth is something good about that person...
Without benefit of astrology, I would say that by keeping one's mouth shut, one does not insert one's foot in it. As the Mexicans say, "En boca cerrada no cae mosca."
There's the story. And my two bits.
Think about what you intend to do before you do something you will regret.
