Ugh Dana, that sucks!
"with some children, you just can't tell them they did anything wrong because they are too sensitive."
I don't get how that's something you'd want to feed or encourage. And I say that as a mom of one of those kids who is prone to outbursts when he's been told he's in the wrong.
We all know these people, right? At work. In relationships. Nothing is ever their fault, there are a million excuses/blames of others for any mistake/failure/rudeness/hurt. Mac has a lot of this despite it not being fed to him at all. He would sooner eat his own face than admit wrong and take responsibility for failures.
So does Isaac (see above), although it's more like he alternates between blaming his behavior on others and earnest soul searching in an attempt to learn and grow and do better.
