The one thing I hate about changing jobs is handing over my stuff to the person taking on my old job.  Its the time when I’ve got to  clean up all those little crappy tasks that I’ve successfully avoided  doing, get my  barely existent filing system into some sort of shape where someone other than me can figure out where things are, and write notes and instructions on how I do various things (tasks that are so familiar to me now that I just do them without having to think about it).
