I don’t know why. I sort of think parents that take an active role in their children's lives and do what they can to help are doing so out of unconditional parental love and support with no expectation of re-payment. You do what you can do to support your child, from feeding and clothing to school loans..
As long as the child has no sense of entitlement and is responsible, then paying for school loans is a moving expression of love and support and an investment in the child's future, as well as their own.
It is nice that he went through with taking care of the mortgage and I find it to be overwhelmingly wonderful expression of love and support.
God Bless!
I see it both ways. Thanks for the other perspective.
