It is often unfair to punish the pupil who laughs in school. People
seldom laugh aloud at their own mistakes. Nine times out of ten one
child must condemn another if he tells what he laughed at. A child’s
code of ethics often demands that he keep silent when his confession
involves another. If his loyalty to his comrades leads him to
disobedience, often the teacher forgets to deal with the real culprit,
having her attention now directed toward the disobedience of the one who
unwillingly brought the disturbance to notice.
