On another theme there is a reference to a whole class recieving the slipper.
What on earth did a whole class do to merit such a punishment?
Having been at school in the same time frame I never could understand teachers logics regarding punishment.
Possible reasons for the punishment of an entire class:
1. The wretched offender did not admit to having committed the crime.
2. Unruly behaviour by an unsupervised class.
