It's shit.
No, really terrible.
It's freezing in winter, boiling in summer, drizzles and is gray for as long as it wants. It is rude, expensive, imperialistic, racist, has a particularly fucked up legal system and the youth of modern Britain are the most horrible group of human beings since the fucking Nazis.
You'll be stabbed, mugged and arrested long before you'll ever reach anywhere safe, and any major city is accompanied by vast industrial complexes and ugly, gray blocks of structures. You can't buy anything without a year of forms and waiting, and nothing gets done until Thursday when it'll cost £Galore.
You can't drink, smoke, gamble or own a sharp bit of plastic unless you're 112 years old and have all the right forms, and even then you couldn't smoke, drink, gamble or own a sharp bit of plastic anywhere but in a sterile environment in your house, because God forbid you anger Health & Bloody Safety.
You can't get anything done because it'll disrupt the cosmic waves of the Earth and it'll annoy the hippies, you can't say anything at all without offending someone somewhere and nothing is allowed because it might hurt someone, possibly if they were in the right circumstances, which means you'll get sued.
And the fantastically shit government will charge you 40% of your money just to be here, before then wasting it on some spectacularly dim project despite the economic difficulties, which in turn will cause yet more taxes to help fund our fucking stupid government.
Don't come to the UK. When I'm done with High School the University it's straight off to USA for me.
