The sins of the father, or why you often get along better with your grandchildren than your children.

You have been a dedicated father, putting the welfare of your children (and your wife) before your own desires, yet your children don’t have a heart for what matters to you, but your grandchildren do? Why is that? “Your grandchildren haven’t grown up around your sins,” says a wise friend of mine.

But in order for that to matter, your children need to lean on their own self-righteousness.
