Are you outside the UK ? She's not the queen of England. She's the Queen (and also Queen of Scotland, Wales, Northern Ireland, Canada, Australia and lots of other countries). :)
Her son, Charles, might remember to send her a card.
It is in a class of self-referential q (actually since she is also Queen of lots of places ! self reverential as well
of the same type as
a barber shaves all the men in the village, does he shave himself ?
you might answer yeh wha ?
however put it as : a barber shaves all the men in the village who dont shave themselves, does the barber shave himself ?
if he does, then he can't be the barber etc.
This led to all sorts of mathematical chaos in 1900s
but also sprouted Godel's theorem.
[ oh and the English dont like the Queen being referred to as the Q of E. Look on it as a fried chicken thing with Tigey. OK to look at but gooey underneath etc....]
I guess no one would send her one. There isn't anyone who has the same prestige that such a telegram would bring.
Btw, I think it's ok to call her the Queen of England to distinguish her from say, the Queen of Denmark or the Netherlands, so we know who you're talking about. It would be a bit ridiculous to name every country she's queen of every time we mention her.
