You bring up a point that, I think, is worthy of more consideration: What is it that exists inside of the people who stay in a place and what is it inside of the people who decide to move on to other places?

The world is full of people who stay, just as it is full of people who move away.

I wonder if anyone in academia has done a formal study on this. My guess is that there is a combination of both genetic and circumstances, just as nature and nurture work together in many other parts of our lives.

Thank you for helping me towards focusing my thoughts on this.

I hope you are enjoying your time in Normandy.
