Kids, a Primer is a collection of a grandfather's musings on the way his (now grown) children are raising their children and being glad about being a grandparent rather than a new parent with young children (again). While Ungar is convinced that grandparents could do a better job raising children if they had the energy, he is grateful that he, in fact, no longer has the energy. Readers will enjoy Ungar's signature sarcastic and witty tone but will be left with a warm sense of gratitude for parents and children alike by the end.
