I think it was Evelyn Waugh who said something about 'the malice of inanimate objects' I think he was talking about such things like the sweeping brush lying in wait for you on the floor which you step on by accident and it leaps up and bashes you on the nose.
One of the worst incidents I ever heard was about the man who went up the ladder to knock a nail into the wooden beam and when it wasn't in the right place and he needed to take it out again, he slapped the wood in his frustration hoping to loosen it and it flew right back at him and embedded itself in his brain. Sadly, with fatal consequences. Minor irritations would be energetically brushing sand from the car seat and being almost blinded in the process or when the toggle on your overcoat gets caught on the door handle firmly yanking you back and making you drop the tray you carry.
What is bugging me at the moment is my profile photo which has somehow blown itself up to full size and appears embarrassingly in addition to my thumbnail photo as a background to all my shared blogs. How it came to do this I don't know only that I've wasted too much time on it already.
Seeking help from Google+ I was directed to Blogger Forum Help by an agent who shall be nameless and when not having solved my problem I turned back to Google+ for assistance encountered this same person again who this time sent me a message asking me how much money was it worth to me to rectify the fault, this was followed promptly by an appearance on screen of the smiling would-be assistant himself who declared that he was now free to personally deal with my problem, estimating upwards of £30 for a successful outcome and a variety of credit cards for ease of payment. At which point I exited the conversation.
