I am not a British citizen yet, but know that I will feel a lot of pride in being one once it will have happened. Maybe people who don't have to go through the whole conscious process of becoming part of a country they've always lived in just don't know how to value it - like anyone with anything that's given to them for free, I guess. I know my parents aren't proud of their home country and I suppose I've never felt pride in my citizenship there, hence why I have arrived in Britain.
I like the British optimism and resilience displayed especially by the older generations. The kind of Blitz spirit attitude that some things in this country may be rotten, but we'll all get through it somehow. The getting-on-with-it personality, who, instead of moaning at quirks such as separate hot and cold water taps, wafer-thin walls and wonky walls either finds a way around the problems or just accepts them for the oddities they are.
I like how that extends to personality quirks. The British understanding of tolerance is such that you barely get a second look, however you choose to express yourself - whether that be rainbow-coloured hair, a full goth look or a body full of tattoos. There was a time in my home country where just wearing a dress on a normal day would get you stared at; so the feeling of freedom here is so much greater.
The British sense of humour is great - dry, dark and to a foreigner quite confusing, as if done well you're never entirely sure whether the person is serious or you're thoroughly having the piss taken out of you.
There is lots more to be proud of, here. I wish people could see how lucky they are.
