It is easy to catalog the causes that lead to excessive attempts to
leave the classroom, study hall, or grade room—restlessness, indolence,
mischief-making, desire to play, conspiracy to meet another pupil,
carelessness in habits of nature, physical ill-health.
Trouble arises over this matter by careless management on the part of
teachers. Caution is necessary at two points: (1) Do not allow too many
interruptions of the work; (2) Do not injure the health of pupils by
refusing necessary privileges.
