NFI,
I am posting to express my disgust at your slur on the Rocks and Plods. I feel it necessary to correct you, and assure you that many of those you slight, have potential far beyond your wildest dreams. Many prominent people started off their working lives as Rocks and Plods, as I did, and am proud of my contribution.
As a former LAC Acting Corporal 'Plod' I did my National Service in the very early 1950s before joining the civil police. Although I had no great academic qualifications I worked hard to get on in my new career and was promoted many times. After a spell as Chief Constable of Thames Valley Police, I became Commissioner of the Metropolitan Police in London. HM The Queen awarded me a Knighthood and when I retired a decade and more ago I was elevated to The House of Lords and subsequently served a tenure as HM Lord Lieutenant of Greater London.
There are more like me coming up through the ranks too.
Now, what exactly is your potential, if you have any ?
