Do not take a rubber toy for a bath. Why bother children with reality? Even if yellow ducks are at stake, it's better to play with them on safe land. There they will keep their class and will look like Mother Nature commanded - with the ridge up and the bow forward. In the water they will show a sad picture of reality - a toy bought, producer happy, disappointed parent. The goal achieved because ... it's just a few zlotys. Not much for parents, a lot for every producer. Nothing, and yet - the problem is.
