I was relieved to be spared the last hour or so of class, and the unpredictably volatile temper of Mrs Ting. At any moment, a blackboard eraser could shoot across the room and strike with pinpoint accuracy the current target of her ire. A hushed silence would follow; a pause for dramatic effect; and finally the pronouncement like an Old Testament prophet that "You have the audacity to…!" commit whatever grave offence against classroom order.
We were a couple of years into the 1980s, but the concept of audacity had yet to be rehabilitated with any positive connotations.
So all up, I didn't mind the job of setting out chairs in the hall for something that was going on after hours. The something was euphemistically called "Life Education". I don't recall being aware it was something I was invited to, but as it turned out, after dinner, my father drove me back to school, and we took our expertly-arranged seats before a projection screen to watch a 16mm film.
