Guille is a very fun child. But that's when he's at home - when Guille leaves his family environment he becomes nervous and introverted. A simple birthday party can become a nightmare for him when his best friend is unable to attend. Trok the troll makes an amusing appearance to help Guille weigh up and reflect on his mistakes. In short: a guide to self-reflection to avoid similar situations in the future. The key focal themes of this story are self-esteem and shyness. A social event can be very fun or very boring, but that depends on how a child approaches it. The characters of the mentors, Chic the fairy and Trok the troll are imaginary friends who guide the child's behaviour and make him think, so each time the child demonstrates poor behaviour, the fairy or the troll will help the main character reflect on this.
