all the time - i think dh is getting used to it, though sometimes he harumphs about it. I figure I'm the one deep cleaning it and using most of it and when it doesn't make sense - I move it. I get input from my five year old.
Though, if it involves dh's things or routine I generally don't touch it without his input. I think every item would remain in place for 50 years if it was up to him.
My DH is the one that moves things around! lol I've learned to go with the flow of it when he gets that whole "lets see how it works from this perspective" vibe going. I actually now LOVE my bedroom and have alot more room in there simply from how he placed things. So, sometimes rooms get moved around, yep.
Moved the living room around again last night and thought of you guys.
DH had moved the couch into one big square to watch a movie, and it was just not flowing with the rest of the room so I had to move everything else around until it just felt better. LOL.
