birthday is in april but they celebrate it in june. that was, because of pandemic rules, done at windsor without the throngs that would normally have been gathered. but the typical meeting would be very formal, of course. i have had the honor of meeting her on several of her washington visits over the decades. in my experience, this is someone who has met with so many world leaders, and she is very, very experienced. she knows so much more than anybody else in history about all of the sort of the range of history, back to world war ii, when of course she was in the british military service, working in the motor pool, and then of course her coronation and all the decades since. so she s very experienced. 13 american presidents, all except lbj, have met with her. joe biden did have a very brief meeting with her when he was on the signal delegation in november of 1982 in england.
