Proud to be British? Share your moments!

I don't go in for jingoism but I sometimes get fed up with the constant criticism of everything we do as a country. Interestingly when I speak to friends who live abroad or I read about other countries they seem to have as many problems as we do. Sometimes similar, sometimes different but I've yet to yearn to live elsewhere. Hopefully this will be a positive thread.
Back in 2012 with the run up to the Olympics the media was full of stories of doom and gloom but it turned out to be a wonderful event and a proper showcase for what we can do as a Nation. I remember watching the opening ceremony, which I thought was so British, no other country would have had one like that, I was so proud. My sister, who has lived in Spain for decades rang me she'd watched it with Spanish friends and they were all enchanted despite not getting some of the references. Whenever I get fed up with the constant complaints I think about August 2012 London Olympics and it puts a smile on my face. Please share your moments!
