It is at least partly a generational thing. Young people don't give a **** about it, in the main. But some old people like it.
My parents are approaching their 60th wedding anniversary and my dad is quite excited about getting a card from the King. I didn't even know that happened....
I thought when the queen died it would have a been a 'bigger deal' than it was. though it was a 'big deal' I was led to beleive everything would be shut down, no telly or radio. they did the classical bit for a little while and took the adverts off but only on a few channels, police interceptors and can't pay we'll take it away was still on repeat constantly.
