I feel my anxiety levels rising when things get messy in the house. I'm not obsessive about tidying, but cannot be bothered with keeping stuff that no longer has a purpose. Our loft has stuff like that, but I cannot persuade himself to rid of it - it's mainly his stuff! Our bedroom doubles up as his "office" when he works at home and there are piles and piles of books sometimes. Does my head in.
Like Susan I have a massive tidy up when visitors are due or I am about to go away on holiday.
