You know it's a good story when:

- you can't eat.
- you can't sleep.
- you can't stop thinking about it.
- you can't go to the bathroom and you badly needed to pee.
- you are a little disoriented after you finished the book because you thought you are one of the characters and you wanted to live inside.    
- your sister is giving you the what-the-heck-look because you can't stop laughing, giggling, squealing, gasping and crying. 
-  you are ready to go to jail because you wanted to kill your sister for disturbing you.

Sorry, I'm just freaking crazy  :D
