I recently returned from a visit to NYC for the first time. While there, I tried to tell my partner about the overwhelming 'citiness' that NYC was exuding but of course I couldn't describe it well. Naturally she shook her head at me. The trip was five days but I was still keenly aware of it into the very last evening. I had difficulty sleeping due to my inability to shut out all the noise -- sirens, honking, the occasional bit of shouting. For reference - I was born, raised, and spent most of my adult life in very small Midwestern towns. We moved a lot when I was young and it wasn't long before I learned to feel the vibes of each different town.
