The following doesn’t relate to any specific incident, it just explains how boys and girls, Naughty enough to be reported to the headmistress at my primary school, were punished back in the 1970s.
When I was at Primary School, spankings for the most part were given by the headmistress, though the occasional smack on the bottom would sometimes be given in class.
These kind of smacks were not that common, however, anyone reported to the headmistress or unlucky enough to be caught in the corridor, if sent out from class, was dearly summoned to be dealt with in the lunch break.
This was bad enough if you got into trouble in the morning, but if you were in trouble in the afternoon, the situation was compounded by an anxious wait until the following day for your punishment.
