Thankyou for your story! I loved reading it. The present Queen has a distinct way of dealing with the public. When she speaks, she repeats the answer people give her. For example;
HM : And what do you do?
Bill : I take photographs for the company Ma'am
HM : Photographs? And are they used in a book?
Bill : In a catalogue Ma'am and we send it out all over the world
HM : How fascinating
And then she moves on. If they continue to talk once she's finished with them, she will repeat, "How fascinating" or she'll say, "Very Good" and laugh as she wanders to the next person. It's a method that means everyone feels she's taken in every word they said and it's a great way. She varies it slightly if she's shaking hands in a line up but it's a good base card to play. Generally, that dialogue lasts only 50 seconds and she spends 5 seconds shaking hands, 2 accepting the bow or curtsey and the other 2 are there in case - that way she spends a minute with each and its fair. I was told this by a former staff member of the Palace who said he was amazed at how she got away with it every time! Apparantly, she learned it from the Queen Mother.
