What is the thing you love the most about being British/the UK?

Ok, I know it's very very vague a question. But I just genuinely want to know. What is, for you, one of the best thing or you favourite thing about the UK or about being British?

I'm looking forward to specific answers, not just "the quality of life is really good in the UK", it is in France or Germany as well as a tone of other developed countries

Have a wonderful day everyone :D
