Wow! I just read in the NYT that there is a possibility of finding this book that I remember ! I believe I read it in the 1970’s or 80’s. As I remember it, it is a  Native American story. A  father does many things for his child. The child says to the father, “when I grow up I will do things for you”  The father replies,” when you grow up the important thing is not that you care and do things for me, but that you care and do things for your own children .” Or something to that effect. The moral of the story being that a parents actions are to teach a child how to be a good and loving person, a parent does not teach a child how to be good using the idea of reciprocity.
