Out of sight, out of mind.
I have the pleasure of having SS's full time and go to their moms whenever (no court order *eye roll*). Well, yesterday BM finally decided that she could take the boys. They left their rooms a mess and stuff all over the living room. I cleaned the living room and threw all their crap in each of their rooms and closed both doors. DH went in one of their rooms and left the door open. When I went and closed it he asked me why I was closing their doors. I just said I'm tidying up and don't want to look at their messy rooms. Part of that is true, but another part of me just puts EVERYTHING of theirs away so I can pretend they don't exist for however long they are gone. One can dream!
