As a child, I used to hear a joke. A father was upset as his little son was not interested in studies. Father decided to make learning fun. He told the child to act like a teacher. Father acted like a student.
The father told his son to teach. He hoped that the son would read book and explain what he read to the father. That way, the child would study something. But the little boy was smarter. He declared, “Children! Class is over! Go and play! Have fun!”
