You're gonna be bothered by how cool I am.

In the movie I definitely saw that the New York (or even, more specifically, Manhattan) as a character theme really stood out with each of Carrie's friends when they were outside of it.

Samantha didn't fit in California as much as she didn't fit in that kind of romantic relationship. (OT but it's easy to ask if she and Smith might've lasted longer on her home turf but I expect the different scenery lengthened rather than shortened it.)

Charlotte's lolarious misadventure in Mexico brought home that she's not truly at home anywhere else.

And then there's Miranda. I still find her arc the most compelling ultimately. Unlike the other three, her resolution doesn't rest on "get our girl home". Maybe she's the one character whose definition of home truly changes and, therefore, she takes the biggest risks and grows the most.

I think you are doing that. You don't just want to make a change for change sake or simplistically chase down a dream. Thoughtfully, feelingly, you realize that you might just be changing your definition of home. Go you!
