The Don't Sweat Guide for Grandparents

Firstly, this is NOT written by Richard Carlson and I don't know how they get away with saying it is.
It is the same message that is in his original Don't Sweat the Small Stuff which I loved, and the message has been rewritten to produce a dozen or more books for various groups of people (parents, teachers, etc) but is a poor substitute for the original.
