Hmm, I wonder if a lot of people moving are moving because they're dissatisfied with their lives, generally, and believe moving will fix that. Which may well be why I moved, on a level, but I'm pretty happy with the move, so whatever ...
I think people having different financial resources is a normal part of life, and your DD will probably be aware of that.

I sometimes go home and am homesick for the UK. I do miss some things, although mostly this time I just missed being home, being in my house. It's been a really chaotic year, my mom died, we had huge renovations, and we spent far too much time away from home.
