This book is not only great for child problem-solving, but adult problem-solving as well. Just recently I thought back to it when distraught as to how to react to being called names as I canvassed for a political organization.
Don't interrupt. Don't call names. Don't shout. Share. Think of how you would feel in that situation. Fulghum was right - there are few problems in the adult world that don't trace right back to the things we were supposed to have learned in kindergarten.
Sadly it's led me to the conclusion that there is little difference between kindergartners and many adults but for that the kindergartners have the chance to grow up.
