General opinion is divided on the matter of tattling on a schoolmate.
Blue law moralists demand that every child and every adult freely tell
all they know against a fellow pupil.
The majority of persons may be trusted to oppose breaking down clan
loyalty among pupils to the degree that any pupil shall be expected to
tell of another’s fault when requested to do so by a teacher.
The wise teacher manages to avoid raising this issue as he nearly always
loses in the contest. It is proper, of course, to ask a class to accept
responsibility for a known prank.
