I used to think the same thing about us. Then I started to look around my garage, I was accumulating a lot of crap because “I might use that again one day “. I had some trips to the dump to make and now I try to do that once a year. We have been here 25 years and there are 6 of us, I would hate to move! But when I start getting older, a few years from death maybe I’m going to become a hoarder just so my kids have a huge mess to clean up to pay them back for never picking up after themselves.
I tell them all the time “putting things away is just the opposite of taking them out”. They can make a meal for themselves, they know where everything is to get it out, when they are done eating suddenly they forget where things go or how to put it away!
