Author's Note 28
Nothing could be more indiscreet than
such a question, especially if the child is guilty. Then if he
thinks you know what he has done, he will think you are setting a
trap for him, and this idea can only set him against you. If he
thinks you do not know, he will say to himself, "Why should I
make my fault known?" And here we have the first temptation to
falsehood as the direct result of your foolish question.
