What've I always said?
A dog that'll BRING a bone'll carry one BACK.
And, like libgirl said, I'd just keep my mouth SHUT and not say a WORD.
As for Robin and Paula . . .
Frankly, if I were in HER shoes, I'd be blurring a WHOLE hell of a lot more than just lines with him behind our closed front door.
And nobody OUTSIDE of our closed front door would know a damned thing until the divorce filing became public knowledge.
But, then again, that's just me.
If, indeed, they're swingers and/or she gives him a football-length leash to do whatever (and vice versa), more power to 'em.
That's THEIR baby, let 'em rock it, THEIR horse, let 'em RIDE it.
It wouldn't be ME, though.
