Covering old ground here but JOP taught me and he was not one to fúck around with. Awesome at encouraging you but cross him or show any disrespect and you were toast. He'd also poke you with the index finger that he'd lost half of. Died about 4-5 years ago. An ex All White who hailed from Laugharne, there's a bonkers place for you.
In Maridunum in Carmarthen (doesn't exist now) we had a female history teacher called "Scratch" due to the frequency she seemed to have an itchy foof. Vanessa Davies was her name, so "VD" became another nickname for her unfortunately.
