My two neighbor girls were searching in my yard. I introduced them to a remarkable item that provided entertainment during my youth. Once you opened it, I told them, you could see words which formed sentences. The sentences became paragraphs through which a lovely story unfolds.
They smiled. I love my neighbor girls!
The book is Judy. A true story of a dog during world war 2.
