    The End?
    —Theodore Simonson. Irvin S. Yeaworth, Jr.. End title card, The Blob, printed on screen at the end of the movie (1958)

    They [parents] can help the children work out schedules for homework, play, and television that minimize the conflicts involved in what to do first. They can offer moral support and encouragement to persist, to try again, to struggle for understanding and mastery. And they can share a child’s pleasure in mastery and accomplishment. But they must not do the job for the children.
    —Dorothy H. Cohen (20th century)
