Moving back "home" after 20 years is a little like dementia-things look familiar but aren't quite the way you remember them. So, you are in an "unknown place" that is familiar.
Moving is always spiritual/emotional for me even though I've done it a million times-there is something very humbling about having all your possessions boxed up-asking yourself "was this what I lived my life for?"
Then there is the big unknown-the what will happen next? Of course, none of us really knows that, do we?
