I found a website online that completly coresponds with the book that i am reading.  In the book i have, it explains how mice go through changes in the book.  The mice are metaphors for people so that the book can be directed towards younger audiances.  the book is about adjusting to changes in your life that are inevitable. Also, it talkes about making changes in your life for the better witch can be difficult.  The website explains issues that can happen with sudden change or gradual change.  the website explains " Adjustment Disorders".  It relates to the book because it shows how people can become sad and depressed and anxious when it comes to changes. The website also touches on stratagies to train your mind to accept changes.  Thankfully that is what this book is trying to do, help with stratagies to cope to this situation :)
