You won't be surprised to know that any association I may have had with Her Majesty, has been pretty remote. I've handled acknowledgements of landmark wedding anniversaries, celebrated by my grandparents. I believe I stood, on a grey day in the late 50s, and waved a small flag as she cruised through, joining the dots where patient subjects lived, to reveal no discernible picture.

I also had a strange experience, finding myself unable to turn right at a junction in Southampton due to the position of the royal car. For a few seconds, I had eye contact with the monarch. No doubt she recalls her own version of events when attempting to lift the mood in the company of overly-deferential diplomats. "Did I ever tell you about the time when I was stuck in the traffic in Southampton? No? Well, you won't believe it, but for a few moments, I had eye contact with Martin Hodges. Philip and I could hardly catch our breath…we were laughing so much."
Invitation from SW
Anyway, unlike our intrepid SW, I didn't follow up the completion of a flattering portrait, with an outright invitation to visit and 'get down' with the kids. SWs spelling is coming on in leaps and bounds, so I'm guessing that 'pru tee' is lining itself up for the urban dictionary as a term for having a 'knees up'.
