It's interesting. I live in London UK, which some might think of as a megacity - though when I look at the biggest cities in the orient (Singapore, Shenzhen etc) London feels like Hobbiton in comparison. I suppose what you're used to becomes your "zero line", and one inevitably assesses other places relative to that.
