I agree, as the future head of state for 16 different countries all around the world, William's wedding is not just a "British" occasion. As a native of Northern Ireland, where half the population think Britain is evil and the other half have their towns painted red, white and blue all year round, it's nice that most people are just happy for the guy and not making it all about politics. After all he's not the head of state yet, just a young man in love.
I will be joining in a street party after the wedding, well it's free food and I'd like to see how all my neighbour's behave when they get drunk, lol. I hope there is a good turn out, in the area of Belfast I live in, there are so many British flags out all year round that no-one can tell which streets are celebrating, lol.
