Master. Because it is wrong.

Child. Wrong! What is wrong?

Master. What is forbidden you.

Child. Why is it wrong to do what is forbidden?

Master. You will be punished for disobedience.

Child. I will do it when no one is looking.

Master. We shall watch you.

Child. I will hide.

Master. We shall ask you what you were doing.

Child. I shall tell a lie.

Master. You must not tell lies.

Child. Why must not I tell lies?

Master. Because it is wrong, etc.
