I’m living in London at the moment. Coming from the US, you’ll probably find it grey, rainy and very expensive. The good bits balance that out, but take a while to find.

Moving to any big city is a culture shock. I found the citizens of London quite friendly, though somewhat reserved. They don’t tend to initiate conversation, but are willing to talk if you are. I really loved the underground!
