Right book at the right time Just a week ago I was talking with my son about his problems on how to know who your friend is in how to behave with those you think are just the opposite. Fortunately he is still in the question phase and having book like this one is a big help. To show, that this question (who is my real friend?) is not so special as kids may think (I have a unsolvable big unique problem nobody can solve). Guess what, they even made a comics book about it. And it is solvable. Fun read with interactive quizzes that flight-check your understanding. Definitely recommended. Parents included.
