It might be some kind of nesting impulse. Most men probably wouldn't get it . But really I suspect it may be a bit of a feminine trait. It's a desire for one's house (or apartment or condo or whatever) to be solace and hiding from what seems a very dangerous and uncertain world (that one must otherwise interact with and sometimes a great deal). And so there is an impulse for it to be nice and filled with nice comforting things.

Now I also have an impulse not to have things, but that is mostly for one reason: because it's easier to move that way and ugh I'm always thinking about moving all the time. So these impulses might counterbalance a lot.

I like outside but that's not always available, work hours too long on workdays, can just walk around the block but have to drive to really get any where more interesting to walk etc..
