Having moved said twat on, with, I hope, the clear message that having been arsed around by work for more than twelve months desk-wise, anyone trying to co-opt my newly acquired office space is going to get short shrift, I was left to ponder just how territorial we humans are. OK, we don't go around pissing on filing cabinets and the like to mark out our territory, but we definitely get very protective as to our personal space. Especially in an office situation. Any encroachment into your territory seems like a threat to your precarious status. It isn't just desks which bring out the territorial instincts - parking spaces are, if anything, even worse for this. I speak from personal experience - it's a real relief that I don't park my car at work anymore. The lack of an allocated parking space means that there's one less piece of turf I have to defend every day. That said, I'm almost as obsessive over my personal parking space. Actually, it isn't just desks and parking spaces - today I got quite irritated when I came home to find that someone had washed down the steps leading up to the terrace my house is situated in. Those steps are actually part of my property and I resent other people taking it upon themselves to do anything to them. If I don't nip this in the bud now, the bastards will soon be emboldened enough to start pissing on my doorstep.
