Il faut toujours dire la vérité
Tip seems to have quite an imagination today, telling all sorts of lies and exaggerated stories to his family. And he's not done when he takes the kindergarten on a field trip. But he'll soon realize that his stories are going to get him into trouble, because if you tell too many made-up stories, people will eventually stop listening to you. It's best to use your imagination in a positive way.
