Okay, I can not hold this in any longer. I have a boxer puppy (Max). I was very tired one night and forgot my math book laying on the sofa. I had a stretch cover on my math book. I wanted to keep this book in the best condition as possible. I had no intentions of keeping the book. Well, you got it, Max ate the cover off and about 1/4 of the spine of the book. I could not believe what I saw. I told my husband, I guess I will be teaching Max math because I cannot return this book. That was one of the very unusual things that happened this term. I have been in school for three term and have had several books. Max never bother my books no matter where I left them laying. It was something about my math book, that Max found irresistable. Good Luck everyone!!!!!!!!!!!!!!!
