Grown-ups embark on a life of deception with considerable misgiving, and generally fail. But not so children. A child can hide the most appalling secret without the least effort, and is practically secure against detection. Parents, finding that they see through their child in so many places the child does not know of, seldom realize that, if there is some point the child really gives his mind to hiding, their chances are nil.
