There is very little I "own" as you outline. Before I moved to NZ things were different. But there is something truly cathartic about moving across the world.
You have to rationalize what you "own" and what you do not care about. We did not ship our "stuff" until after 6 months of getting to NZ, by then a container turns up and then you question "why did I keep this?" as you open all the boxes lol
I care about my wife and my dog. I care about family but they are far away now which distances you in ways over the years.
I care about my data such as all my photos etc as they are really memories. Things that are hard to replace. But nowdays, stuff... not so much.
Probably living long enough that you have owned a certain "thing" many times as you replace old/broken things.
The less you "own" the better imho :)
Haha, I can very much imagine the "forgotten box feeling". This should be an expression.
And I personally find owning stuff very stressful.
The most insane feeling of all is not having a key to anything! I realized that sat in the UK waiting to board the flight to NZ. At that point neither of us had or needed a key to open anything.
That was the most detached feeling ever. :)
