Your description of London is fantastically spot on in my opinion! I moved there three years ago where I undertook my degree and the city gradually sucked the life out of me. I didn't build up much familiarity in any single place and couldn't wait to leave. Everyone appears so sidetracked with making money that they forget about the importance of their own true happiness, it just feels like everyone is existing with no real purpose. I found the disconnection you talk about to be frustrating more than anything. I became so overwhelmed with feelings like this and that may be partly why I have become so interested in your teachings.
