All in the beat possible taste my friend. Maybe Mrs Brown would be kind enough to give you the plimsole after you had watched her give it to a line of girls first, we can only dream eh?
Failing to attend a detention she'd been given for not doing homework on several occasions resulted in her first punishment. Her second caning came about because she had been warned that her school work needed to show a significant improvement before the end of term. Poor results in her end of year internal exams lead to her second thrashing in six months. In 1975 things were very different to today, that's for sure.
