Cleaners see all. I've seen a very similar scenario. Allow me to present a case study, anonymized of course, so as not to PL.
This family had more than one kid, but the eldest kid got the biggest room, which led to some tension with the younger ones who felt it wasn't fair. Except it turns out the eldest didn't get to use all of "her room" because it's actually where the mom was storing her hoard. It was only when the hoard started spilling into the other rooms of the home that the younger children realized what was going on.
This was years ago, mind you, and of the children all ended up with some form of minimalist tendencies and weird behavior towards their belongings.
Cats know the true value of pussy isn't measured in simpbux.
Also, Alinty is weak, WEAK!
