Not sure I'd use the word pride, there are certainly things I like about my country but I can't take much credit for them.
Some things I like:
Our "Freedom to roam" laws and customs. which go a long way to making sure our country is actually our country.
The general geekiness of our culture.
That we've stayed away from wars for 200 years.
I would also like to take this opportunity to apologise for IKEA.
What? You aren't supposed to be proud of anything, you are neutral damnit!
