Britian is my home, the North of England to be precise. I fully understand what you mean by saying that you're frustrated. It sounds to me, like you're probably stuck in the city proper. I couldn't thnk of a worse fate.
But, honestly, what you're seeing is a microcosm of all that is wrong with Britain at the moment. Do not let that be your memory of Britain when you leave though. Becuase it is so much more and so much better.
Take BW up on his offer, get out into the more rural parts, remember you're never more than 4 hours from the sea in the UK. Pick a direction and find your whole world transformed.
Yes, by all means b*tch and moan. (we all do it, stand in a queue for a late bus, you'll see what I mean.)
But also remember, it is our home and Brits are very strange like that. We can slag our own home off as much as we want, we think it's our right. After all, we were unlucky enough to be born here, <grumble grumble> but nothing makes our blood boil more than hearing a non native slagging it off. No matter how valid that person's points may be.
