It will resonate in his mind...
What he DOES with it is a roll of the dice... but the truth darts can get in there... It has to be quick and sharp.. the one I wrote above is probably a bit wordy... But its a draft at least...

I think it was PDT's who used this on his wife. He had told his wife she wans't just a bad wife, but a bad mother (she had been neglecting their kids)...
After that her attentiveness to their children improved. She did NOT end the affair, or say anything by way of agreement, but it did sink in... even if she never admitted he was right
