We must have been separated at birth. Same here. Too much stuff; busy clearing things out and throwing stuff away. The problem was that we moved from a 120 sq.m.-apartment to a 68 sq.m-one.

Now, my friends say I keep a clean neat place but they dont know that my closets and drawers are quite full.
What I did was bluff my way through tidying up. Stuff chaos in box. Put box in wardrobe. Close door. Voilà! It drove my Mum NUTS. I still do it, btw.
