I have no idea. The first time I left a country (not my home country - I was born outside of the US), I was less than a year old. Then I moved around every three years or so, sometimes less, for my entire childhood. We flew back to the US for vacations. When I was in college, I flew to see my parents twice a year. Then I lived overseas again after that.
So a lot.
It is the light she longs to find,
When she delights in learning more.
Her world is learning; it defines
The destiny she’s reaching for
