How to Tell When You're Really Old is the result of hundreds of interviews with young children ages three to twelve, who were asked to explain how they could tell when someone was really old. It began as part of a larger class project by teacher Kristi Porter and the children of Happi Kamper Child Care, located in North Muskegon, Michigan. Each child was to create an individual gift book for his or her parents, and How to Tell When You're Really Old was simply to be one chapter in each child's book. Now, the individual answers of the Happi Kamper Kids, as well as those of the children at Community United Methodist Preschool, and the kids of Power Play Childcare have been combined. Their candid, uncensored, and often hilarious answers will not only make you rethink the aging process, but are sure to become instant favorites, as you get a quick glimpse into the amazing and intricate minds of some of the most delightful and fascinating children around.
