I am a teacher, reading this book aloud to my class. We have had some wonderful discussions, not only about how to be a friend, but how to be someone going through a tough time, as well. If you have never been through something hard, you may become confused, angry, quiet, or over-compensate with joy. We talked about how all reactions are okay. However you are feeling is how you are feeling, and that is okay. I think this discussion was really appropriate and helpful for my kids.
I have read this book personally and with my students. It is wonderful. There is no better real world connection in literature. The students love it! It talks about issues that most students go through or know someone who has gone through them. It has been a very beneficial book for my classes. I would not recommend this book for anyone under the age of twelve.
