I shall never forget what I saw at the Museum of Modern Art: in a spotless schoolroom, fifty little girls painting away at tables covered with brushes, pots, tubes, bowls, staring into space and sticking out their tongues like the clever animals that ring a bell, tongues lolling and eyes vague. Teachers supervise these young creators of abstract art and slap their wrists if what they paint represents something and dangerously inclines toward realism. The mothers - still at the Picasso stage - are not admitted.
