The teacher who owned it went on to become the Principal of a school in a surburb not far from where I now live. I’ve been tempted to retrieve it and mail it to him with a note saying “This belongs to you. I can’t understand how you managed to misplaced it. Four Kilometers from the classroom. We don’t have CP in our schools now so it would be useless to him now.
We kept a low profile for a while after that and I think it was two years later when Phil struck again, putting him in the lead.
On another occasion, I remember we were having a PE lesson and there were benches on either side of the entrance hall to the gym where the boys who had excuses for not attending PE sat. There were narrow windows at the top of the wall on on side which looked into the PE office.
