Its when papers are at 45degrees, occupy every flat surface, you sometimes have to balance your computer on top of a pile of books because all space is occupied, the cat manages to squeeze in between two piles of papers, and then wiggles and wiggles to get comfy and sends both piles flying - or - as I found at work today, you know there is a piece of paper on the desk with some vital info on it and you can't find it, you search through all the odd bits of paper several times, and even go to search somewhere else even though you know it is on the desk, and then it just appears in the pile on the desk, out of the blue - how does that happen then???? On the other hand I can't work in a really tidy place...well that is my excuse anyway and I'm sticking to it too.
