I laughed so many times as I read this book. Mr. Dahl has a ready wit that I remembered gradually from his other books as I delved further into this one.
While Mr. Dahl relates many stories from his childhood in this book I wouldn't call it an autobiography. Instead, I believe that Mr. Dahl...like my grandfather...elaborated and created full stories out of pictures from his memory.
Still, those elaborated pictures were quite enjoyable. I couldn't help but compare Hogwarts to Mr. Dahl's schools and see how the English school system is so much different than the US but also how "uniform" English schools are. I hope you know that I don't mean that all of the school are the same but that they have as a similar structure in contrast with a public high school in the US.
Throughout the book pictures are interspersed with handwritten captions...presumably handwritten by Dahl himself. Somehow this makes me like the book even more.
