Wrong book?

I don't understand I seem to get into mummy's wrong book ? Ehh......I mean all I did was to tear the book that is left permanently in the car, coz' I wanted to show mummy that I can do it! She's always telling che-che to be more participative. I am! But I think I did it the wrong way.

Now, mummy's grumbling that she has to stick back the pages.
