I have just accidentally tipped coffee over a particularly hated job bag containing piece of work which I have taken a week and a half longer to complete than I should have done, purely because I don't like doing it. This makes me believe that malevolent forces exist on Wednesday mornings. Unfortunately the coffee also went over my leg.
[pen] Have you noticed how coffee expands when freed from the constaints of a cup/mug? One knocked over mug of coffee can flood an entire desk, soak into reams of paperwork and fill a couple of drawers.
