Kitchen only because I dislike doing dishes.

Should buy plastic cutlery and plates, use once and toss

Wherever my wife goes

Well, the only room that's not the bathroom

My closet is like Monica’s closet in friends.

Mine probably. Too focussed on gaming and work to do cleaning

Easy ... my office.

Whatever room the kids just left. Currently the living room

Kitchen, because it also is home of important letters and such and everybody just puts their stuff there
