One of my cousins teaches at the University of Louisville, in Kentucky...and my aunt says he is the same way as my son...he has piles and piles of stuff everywhere...and that is his system....His wife, tho, is the opposite, and likes everything neat and clean and sparkling
So they have a deal...he wont make a mess in the rest of the house, so long as she does not fiddle with, nor complain about anything is his office at home....And my aunt says, that he just has hills and mountains and stacks of stuff everywhere in his office. And he is happy as can be in there...and his wife never enters, and just closes the door, when company comes to visit...
Doors have a good purpose, they can hide the clutter that drives other people mad...
