I don't think it's about not wanting to look at things - my wife once moved something from me from the bathroom above the sink to a shelf, and I got pissed I couldn't find it. She said it was too much stuff there. I then went there and counted 17 things that belonged to her, and 2 that belonged to me, 1 of which was apparently too much.

In my experience women do this a lot. I don't know if it's some kind of an evolutionary thing. On the one hand that it was something women traditionally did and can't let go, on the other that it is/was a way to make themselves more important. You become very important when somebody needs you all the time to tell them where things are.
