I'm more of an influencer on my kids. I don't have authority. What I do have is time attention and joy at being with them.
I did not cause my ex-wife's anger and depression. And I'm not causing it now. And the money is not going to fix it. You can't rub money on a lifetime of depression. Sure, the new car will be nice. And, sure, she and her husband won't have to balance the checkbook as carefully.
