Constitutional monarchies work pretty well as a form of government - Canada, New Zealand, Australia, Holland, Norway, Sweden, and Denmark still have a royal head of state, however irrational this look like on paper. It's this kind of razzmatazz that makes it look sillier than it is. I avoided the shindig yesterday however saw the 3 minute highlights to catch Megan's very becoming dress.
Don't mind people partying for this kind of patriotism as it's a light-hearted affair, and everyone likes a wedding.
The last one I was cycling in England - staying in Saffron Walden with a friend. We went out for a cycle and the pretty villages looked very jolly hung with bunting, there were Maypole dances and Union Flag iced cakes and it was cheery and good-tempered. In the end we were miffed we had not joined in with the local street party and drunk beer and eaten sausages with the neighbours.
