I really loved this book. A beautiful book full of easy to understand and process information for all ages. My son loved reading this one with myself and my husband. As a child with a white Mother and Biracial father my son was amazed that not everyone thinks the way of message of this book already. It's full of beautiful illustrations & my son loved learning all the different ways you can say hello, he enjoyed pronouncing them & trying to remember them so if he went to those countries or meet someone with that language, he will be able to say hello in their language. All round a beautiful book that should be in every household, library, and school. My husband, myself and my son all give it 5 out of 5 stars.
