Have you ever been misunderstood? It happens to all of us at some stage in our lives.
Do you think Jesus was misunderstood? Sure He was! The Jews were convinced that He was going to physically break down the temple.
Of course, children are misunderstood all the time, especially when they are still small, before they have mastered the art of reasoning and explanation. Heck, some adults haven't learnt that yet.
This teacher obviously did not have a clue!
