Could the story be true? Who knows? It makes us think though of Jesus as a human boy, poised for small mischief like even good boys are by their nature.
The story is also about St. Joseph, chiding Jesus to remember and obey the Sabbath, but he does so without being wrathful and punitive. Surely there are fathers who would do better to take more of that approach to the inevitable misdeeds of their children.
Jesus never sinned.
He could not have, or rather would not have, done *misdeeds* or mischievous things.
