A little boy is tired of following the rules and thinks he can escape them... by growing up! But what makes a grown-up?

When you're little, you have to follow the rules. For example, you're not allowed to eat madeleines in the bath, or eat the whole packet at once. Our hero is tired of following rules that prevent him from enjoying life (and madeleines), so he decides to grow up. And what's the difference between kids and grown-ups? Body hair, of course! If he had body hair... everything would be easier. A tender and humorous picture book about the quest for freedom!
