The class was coming to an end. The teacher told the pupils not to draw anything on the wall in order to keep it clean.
After class, David forgot the teacher's words. He took a piece of chalk and drew a sun on the wall. Just then, he noticed that the teacher was coming back again. So he quickly covered his drawing with his back. The teacher didn't find out what he was doing. When she passed, she smiled at David. David was very happy. But when he turned around to see his drawing, he found nothing on the wall.
Where was David's drawing?
