I think when it comes to family or even close friends, I would have done the same as you rit.
I would have wanted to give them the benefit of the doubt that they would hear my words, respect them considering the source, and do the right thing.
I would have been dealing with this with emotions, rather than logic.
Not so close friends or not family, no emotions involved, I wouldn't give exposure a second thought, I'd be using logic.
I wouldn't want to believe that they are as wayward and selfish as what I saw in my own WS, (or reading here) even though I listened to to him and rolled my eyes.
So hindsight is 20/20, lesson learned and not to be repeated.
Based on your experience, I would expose without warning, so thank you for sharing.
I hope that Joey's sees how doing the right thing, trumped your fear of his anger and isolation.
