It’s not the “self supporting” that defines his responsibilities for himself. It’s the age and the stage, assuming he is not disabled in some diagnosed way.
One of the hardest lessons (and I know I’m not the only one to go through this,) is when you acknowledge that fixing for them- or reminding, suggesting, researching, pressing- doesn’t help them mature. Sometimes, the only way for them to grow is for them to take responsibility for their own mistakes. (Not just the events of the arrest, but the decisions and actions- or lack- since then. His own choices.)
Unfortunately, unlike much of the younger parenting, we can’t spare them, they have to experience this themsleves, to own it.
GloriaVaughn, I had to have some background check to work with “kids” - grad students.
