"I can only imagine a situation at a play school or a nursery school where the nursery teacher has to try to keep a check on which children are under and which are over three years of age as well as which children are allowed to put what in their mouths in accordance with all the experiments the Commission is trying to include."
J'imagine la situation dans les crèches ou les écoles maternelles, après toutes les tentatives actuelles de la Commission, le jour où le personnel aura à se demander quels enfants ont plus ou moins de trois ans, et lesquels ont le droit de porter les jouets à la bouche.
