Harmful Advice. Part 2

Scientists have proven that harmful advice acts on children like a vaccine against stupidity. Disobedient children will act contrary to this advice (and it will turn out as needed), while obedient children will read and understand that they should never do that, of course. G. Oster's book «Harmful Advice-2» with illustrations by A. Martynov is suitable for all children. Laughter and good mood are guaranteed! For younger school age.
