My two year old cousin had a “precious” book of hers that depicted all types of animals. Since this book was so precious to her she read it over and over again until she knew the names of all the anials and how they look.
One day my aunt was leaving a store with this child and an african amerian was kind enough to hold the door open for them. My little cousin cheerfully waved goodbye to this man and then (loudly!) called, ” Bye-bye gorilla!”.
